Cool to see this posted. I've been using it for the past few weeks while making some simple 2d games Godot (my winter hobby).

Overall it's been pretty good. Sometimes it slows down during tasks (a lot more than Photoshop or Clip Studio do while doing things like transforming a selection) but most of it works well. The animation features have been handy and were just simple enough to be useful.

If you're having performance issues on non-Windows, you might try twiddling around with the UI options. In particular, setting "Screen Scaling" to 100% and "UI Scaling" up to 200% to compensate seems to vastly improve performance on both my Pinebook, and even my gaming rig with a reasonably beefy AMD graphics card. I'm not sure why it makes such a big difference, but it's night and day for me in terms of jank and overall smoothness.
