OutdoorLabel Motion Title text font becomes small when a legacy project with this title is opened in PRE2021.
If a project is created in Premiere Elements 2020 (or earlier) with OutdoorLabel Motion Title, and the legacy project is opened in Premiere Elements 2021 with hardware acceleration on, the font of the title becomes small.
Replace the existing OutdoorLabel Motion Title applied in legacy project with the same title in Premiere Elements 2021.
Open Preferences > General. Uncheck Use GPU accelerated effects, transitions & workflows on selected GPUs for improved playback & export performance. Close and relaunch PRE. Now reopen the project in Premiere Elements 2021.
