Graphics Glitches on Windows


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.


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.


  1. 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.
  2. 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.
