Hi all. There's a test build now up on the beta branch. This has some potential fixes for the game not generating a Thumbnails folder on first setup, Stamping in Mondrian Maker not painting blocks the color in the main swatch when the Shuffle Button is off, maximizing the window fullscreening the game (now maximizing leaves a header bar), and ugly extra bleed space around the frame when capturing thumbnails with the window maximized.
Maximized captures will still give a slightly wider result than expected (for instance, a 1x1 capture will be more like 1.05x1) just due to the nature of the window squashing because of the taskbar. Overall then I still recommend capturing your thumbnails in either Windowed or Fullscreen mode (Alt-Enter works just fine), but you do you.
Ideally I'll push this build to the default branch in a week if there are no other issues, but let me know how it works for you in the meantime. Thanks!
