That's pretty weird; both Gimp and Krita (very different tools) were rock-solid to me. Speaking of KDEnlive, I experienced a few anomalies and crashes using the version from my distro; I switched to an AppImage version, and with it, everything Just Works™.

I suspect your crashes may also be related to dependencies, not some deficiencies of the application itself. Try a different build / AppImage / Flatpak, and see if you encounter the same problems.
