It's happened to me several times, and I'm not sure how to troubleshoot it this time around, the worst part is that I've skipped a couple of versions so I can't tell which version introduced this issue. I'm currently browsing through older versions to see where the issue began (and also to find a usable version until this gets fixed... I hope this issue gets some priority, this is the only program I can draw with on linux, seriously, everything else is garbage :/ I tried going back to krita earlier but I just can't man, their brush engine is so slow and no matter how I tweak it the basic brushes just dont' work the way they should.)
I do need a link to version 2.40.1 though, I couldn't guess the download url for it (it's not https://paintstormstudio.com/Paintstorm ... run.tar.gz like I thought)
(Edit: It seems that the issue does not seem present in 2.40, but is present in 2.42, all I need now is to know if it's also in 2.40.1 and we can narrow down what version the issue started with)
It'd be nice if other linux users chime in and share if they're having (or even if they're not having) this issue.
