Graphics Glitches on Windows
Condition
The moving playhead leaves trails on screen, gray lines appear inside content when scrolling a view. Fonts do not display correctly. This happens on Microsoft Windows with high DPI monitors only.
Cause
Odd DPI scaling factors like 175% or 225% cause misalignments through rounding issues. Synfire has problems addressing quarter pixels, so to speak. We have not yet found a solution that works with all DPI settings.
Remedy
- The glitches go away when you set your monitor's DPI scaling factor in the Windows System Settings to 100, 150, 200, 250 or 300 percent.
- Alternatively, you can disable HiDPI for Synfire altogether by editing its desktop shortcut: Append the command line option -H after the program name that is written in quotes.
