Bug ID: 475642
Summary: Transparent XWayland Windows can have strange
artifacts, demonstrated with Oneko and Neko98.
Classification: Plasma
Product: kwin
Version: 5.27.8
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: platform-x11-nested

A screenshot of both Oneko and Neko98 with identical artifacting.
SUMMARY
On Fedora, running Oneko from the repos, from Flathub, or running Neko98
through Wine results in overlapping frames of animation. They look just fine on
the standalone X11 session.
I had a friend of mine running Gnome 44 on NixOS attempt to install and run
Oneko, and it looked just fine on Wayland, so I'm guessing this is a KDE
specific issue.
I've managed to reproduce it both on my laptop with an AMD CPU/GPU, and on my
tablet with an Intel CPU/GPU.
STEPS TO REPRODUCE
1. Run Oneko on KDE Wayland
OBSERVED RESULT
I've attached a screenshot, they look very wrong.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Fedora 38, KDE 5.27.8
