Yeah, drawing in photoshop is one of the reasons I haven’t switched my laptop over to Linux even though I have with both home PCs.I don't know if it's a FOSS issue or not, but usually the awkwardness of programs like that (GIMP, Inkscape, and probably many others) are some of the reasons why I can't quit Windoze cold turkey, even though I really like the idea of just using Linux for everything, including but not limited to vector and raster editors.
I know that anyone could theoretically just crack it open and fix what they don't like, but that would take me years
