Screen flickers while writing in a PDF on Windows 10 touchscreen devices

On Windows 10 touchscreen devices, screen flickers while writing or using a freeform Comment tool in a PDF.

Apply the registry fix on your Windows 10 touchscreen device

The registry fix suggested below does the following: In Adobe Acrobat Pro, under Computer\HKEY_CURRENT_USER\Software\Adobe\Adobe Acrobat\<TRACK>\AVGeneral, it adds a DWORD named bDirectInkingEnabled and sets its value to 0. (Here, the <TRACK> can be DC or 2017.)


  1. Quit Acrobat DC or 2017 application if it's already running.

  2. Download and save the appropriate file based on your Acrobat version (DC or 2017):


  3. Unzip or extract the content of the downloaded file (.reg file) in a folder.

  4. Make sure that you have administrative privileges. Right-click the .reg file and select Merge.
