So what design tools do you use now? Browser based?
i'm not a designer, but use Krita for very basic edit tasks and Inkscape on occasion. can't use GIMP well because it's GTK2 and the UI doesnt work well for pixel-scaled (HiDPI displays), and GTK3-based GIMP 3 dev builds often fail to compile: https://aur.archlinux.org/packages/gimp-devel
switched to Arch (EndeavourOS KDE/Plasma) and life is sane again; enjoyable, even!
i do miss Affinity products, tho, which cannot even run in Wine/Proton :(
