I think i found a goldmine to completely ditch proprietary software (including Affinity) for photo editing on Linux.
So after weeks of searching through internet, i found great tool (well, actually Krita plugin) for replacing AI features for free (locally!) that previously was one of only good thing that tied me to proprietary software.
And as bonus there is pretty well-known tool for upscaling your pictures (require GPU) or if you have weak hardware you can try this util (slower)
I hope this will help someone. Especially first tool.
