BUG? - Some apps replaced by black rectangle when starting

Fedora Workstation 38 and 39 (Gnome, Wayland, AMD cpu and GPU, issue present since install in September)

Some apps show up as a black rectangle when launching. This looks quite jarring and also obscures custom splash screens that may show information.

Known affected apps:
PrusaSlicer (GTK3 Appimage, versions 2.6.1 and 2.7 tested)
Darktable (rpm, 4.4.2)

Is this a known issue? I could’t find anything when searching for it. The apps do work fine when they’re fully launched.
