Clip Studio is close - really close, but color selection doesn't work and touch controls are messed up (especially with the stylus eraser). Touch support in Linux in general is awful, even with apps that I expect better of like Firefox or MyPaint, but it's almost good enough that I could tolerate it and switch anyway.

I'm semi-hopeful that it'll cross that line in a year or two, and especially hopeful that the work Purism is doing on the Librem Phone might speed that process up.

I honestly haven't tried to run a VM, I just assumed it would eat up battery too much to be useful - and since I use the tablet specifically for these apps, I'd have to spend all of my time in the VM anyway, which doesn't seem like much of an improvement :)
