Quick Question - Were you using the OpenGL Renderer on Wayland? You can check which renderer is in use by going to Settings > Configure Gwenview > Image View > Animations. If it's set to OpenGL, try changing it to Software. That should help for the time being.

A fix for the OpenGL renderer got merged yesterday - https://invent.kde.org/graphics/gwenview/-/merge_requests/37

It will be available in Gwenview v20.12.3
