not clearing image buffer on wayland for the 3D renderer

[dottedboxguy]

running the software on fedora 44, gnome with wayland, AMD rx7600

the app is not clearing the background, which is rendered with alpha 0, causing severe rendering issues as seen in linked media.
the effect is not seen in screenshots which get taken with alpha, meaning the rendering artifacts are invisible.

Thanks for finding this issue. Are you compiling the main branch or the migrate/qt6 branch?
