Known issues, bugs | Photoshop CS5

Welcome to Adobe® Photoshop® CS5. This document contains known issues and troubleshooting tips not covered in the Photoshop documentation. 

See Adobe Support for late-breaking information and known issues for all Creative Suite 5 applications.

64-bit issues

On Macintosh only, several plug-ins are no longer supported for 64-bit systems. These plug-ins run in 32-bit mode only:

• Embed/Read Watermark
• Lighting Effects
• Send Video Preview to Device
• Variations
• Video Preview
• Optional plug-ins (Contact Sheet, Pattern Maker, PhotomergeUI, Web Photo Gallery).
  Note: These plug-ins are not included in your Photoshop CS5 install. You can find more info in  Plug-ins | Photoshop CS5. This download package contains the plug-ins along with the Optional Plug-ins ReadMe.

You can encounter instabilities with some third-party Carbon plug-ins from CS4 or earlier. Adobe recommends that you do not copy third-party plug-ins directly to the Photoshop Plug-ins folder. Store these third-party plug-ins in a separate folder and then loaded via Preferences > Plug-ins > Additional Plug-ins. If instabilities occur in the app, either through general use or when using a plug-in directly, follow the plug-in troubleshooting in Troubleshoot plug-ins | Photoshop CS4, CS5.

The Extract plug-in is no longer supported in Photoshop CS5. Adobe highly recommends that you use Refine Edge and the Quick Select Tool for optimal selections.

To support the display of all characters of the Chinese standard GB18030 on Windows XP systems, Adobe recommends using the Microsoft GB18030 Support Package. This support package updates an XP system with, among other things, fonts and input-method-editors (IMEs) to correctly support GB18030. The support package is available as a download from the Microsoft website.

Photoshop CS5 supports video card acceleration by using the video card's graphics processing unit, or GPU. For more information about GPU and OpenGL support in Photoshop CS5, see the following documents:

• GPU and OpenGL support | Photoshop CS4, CS5
• GPU and OpenGL features and preferences | Photoshop and Bridge CS5, CS4
• Tested video cards | Photoshop CS5

All How-To links have been removed from Photoshop CS5. 

This plug-in is now included in the Photoshop CS5 default install. It's no longer necessary to install it (from Photoshop CS4) as an optional plug-in.

• PDF Contact Sheet and Web Photo Gallery can be found in Bridge CS5 in the Adobe Output Model (AOM). If you want to download the Photoshop CS5 versions of PDF Contact Sheet and Web Photo Gallery, see the following document for information: Plug-ins | Photoshop CS5. This download package contains the plug-in along with Optional Plug-ins ReadMe. 

Note: The Web Photo Gallery plug-in does not work in Photoshop Mac 64 bit. Launch Photoshop in 32-bit mode to use this legacy plug-in on the Mac.

• \Pattern Maker, PhotomergeUI, and Picture Package are also not installed in Photoshop CS5 along with the Textures and Layouts presets. If you want to download these plug-ins, you can find them in Plug-ins | Photoshop CS5. This download package contains the plug-in along with Optional Plug-ins ReadMe. 

Note: ContactSheet, PatternMaker, and Photomerge plug-ins do not work on Photoshop Mac 64-bit. Launch Photoshop in 32-bit mode to use these legacy plug-ins on the Mac.

Other Optional plug-ins:

• FireWire and FireWireDLL are supported only on 32-bit systems for Mac OS and Windows.
• TWAIN for 32-bit Mac OS and Windows (see below for more information)

• Mac OS users with more than 4 GB of RAM who are running the 64-bit version and processing large files can see significant performance improvements by using the "DisableVMBuffering" optional plug-in. Download the plug-in from from http://www.adobe.com/go/ps_cs5_plugins_mac_en or http://www.adobe.com/go/ps_cs5_plugins_win_en and copy it to the Plug-Ins folder within the Adobe Photoshop CS5 folder. (Large files are files cause access to the scratch disk as indicated by the "efficiency"indicator in the document status box often dropping below about 95%.)
• Windows users can experience slow redrawing of windows, user interface around windows and,  tiling of windows (Window >Arrange >Tile). Adobe has found the cause of this issue to be desktop Themes applied to your OS via Desktop options > Personalize >Window Color and Appearance. For Windows XP, disable any Themes you have applied. For Windows Vista, Adobe recommends using the Aero Theme with desktop compositing enabled. All other themes are likely to result in this problem. For Windows 7, Adobe recommends that any Theme with desktop compositing enabled. If this option is not enabled, user can experience this problem. In general, Adobe recommends that you try a different Theme outside Aero for Windows 7 users.

• Bigger Tiles has been removed from Photoshop CS5 as the functionality has now been built in to the performance preferences. This setting can now be set in the user interface. Set "Cache Tile Size" to 1024 K or 1028 K in the performance section of Photoshop preferences.
• Filmstrip format (plug-in) for 32-bit/64-bit Macintosh and Windows systems has been removed from the install. In addition, it is no longer available to download.

• If you try to save named slices to a directory where that filename exists, Photoshop doesn't prompt you with an overwrite warning. You silently overwrite the existing file.
• Adobe has removed the shortcut used to delete the preference file for Save for Web in Photoshop CS5. To manually delete this preference file, navigate to the following locations and delete the Adobe Save for Web 12.0 Preferences file:
  
  Windows XP: C:\Documents and Settings\username\Application Data\Adobe\Save for Web\12.0\Adobe Save for Web 12.0 Prefs
  
  Windows Vista or Windows 7: C:\Users\username\AppData\Roaming\Adobe\Save for Web\12.0\Adobe Save for Web 12.0 Prefs
  
  Macintosh: Volume\username\Library\Preferences\Adobe Save for Web 12.0 Prefs

Important: Apple made the user library folder hidden by default with the release of Mac OS X 10.7. If you need access to files in the hidden library folder to perform Adobe-related troubleshooting, see How to access hidden user library files.

• Photoshop CS5 can read tool presets created by earlier versions of Photoshop, but earlier versions of Photoshop cannot read tool presets created by Photoshop CS5.

• If you are using the NVIDIA GeForce 7300GT, you can experience performance issues when editing text, especially on large documents. Adobe recommends that you upgrade your video card for a better experience. For more information on this card and support options, see the GPU guidance document in GPU, OpenGL support | Photoshop CS4, CS5. This card is problematic for many areas in Photoshop and Adobe suggests that you contact the manufacturer for more information.
• The Japanese text input mode Koteoeri/ATOK is not supported on Mac OS 10.5.x and earlier. You can experience slowdowns and lack of response when attempting to use this input method. Contact Apple support if you would like more information. Adobe recommends that you upgrade to Mac OS 10.6 to resolve this issue. 
• The legacy shortcut to duplicate and transform (Cmd + Opt + T) on Mac 10.5 now opens the Character panel.

• Photoshop does not install the TWAIN plug-in for Photoshop CS5.  For information on TWAIN support and download, see Plug-ins | Photoshop CS5 or contact the manufacturer of your device for further TWAIN support. The download package contains the plug-in along with Optional Plug-ins ReadMe for Photoshop CS5. Do not use the TWAIN plug-in from Photoshop CS4 downloads.
• 64-bit Support: 64-bit TWAIN scanners are not officially supported in either 64-bit or 32-bit Photoshop. Use at your own risk. However, Adobe has found that the Canon PIXMA MP990 (64 bit) works well on both 32-bit and 64-bit versions for Mac OS 10.6. If you use a TWAIN scanner, Adobe recommends that you use this scanner and upgrade to Mac OS 10.6.

• The Nvidia GeForce 7300GT is a problematic card, especially for 3D in Photoshop on Macintosh OS < 10.6. You can experience frequent crashes as well as limited functionality. Adobe recommends that you upgrade your Macintosh systems to 10.6 for a better experience.
• Adobe Repoussé is dependent on OpenGL; it's necessary to have a OpenGL supported card. See Tested video cards | Photoshop CS5 for a list of supported cards and troubleshooting tips.
• 3D objects imported (OBJ and KMZ) with missing textures sometimes need to have their Opacity manually changed to 100%. Many applications export objects with Opacity set to 0% and therefore Photoshop reads this material as fully transparent.
• When you create holes using Adobe Repoussé from type layers, you can experience missing geometry on the front face of the mesh. This issue occurs if the font size is too small relative to the hole.
• Image Based Lights do not have a specular component; gloss, and shine maps don't have any effect.

DAE/KMZ mesh/model pieces sometimes show up in the wrong place. This issue occurs because Photoshop doesn't create meshes for polygon types like Lines and Points. In addition, because the mesh hierarchy is not accurate, transformations may not be in the right place. Unfortunately, as Photoshop doesn't support lines and points in its renderer, Adobe currently doesn't have a way to resolve this issue.

Google Sketchup 7.1 changed the way they export their Collada format. If you have a Google 3D Collada file (DAE/KMZ) where it opens with missing meshes or textures, reexport the file from Sketchup 7.1 or later with the Export parameter "Preserve Component hierarchies" deselected.

Models exported from Poser often come into Photoshop with Opacity of textures set to 0%. To view these textures, simply change Opacity to 100% for all textures.
