Have you tried --use-angle=gl? A similar bug to this existed in previous versions (115 and 119), and it was a compositor bug that occurred regardless of renderer, but it was fixed.

Have you tried --use-angle=gl?

I've tried it just now, unfortunately it didn't work.
It glitches the same way regardless of which graphics engine I use on #use-angle flag.
Also it's the same with the new release version

btw is graphics acceleration supposed to work at all in Vista right now, because it never did for me and it falls back to software rasterization, so it doesn't get to use any of this OpenGL/DirectX stuff if I'm not mistaken.

Ok, I've tried some of the soluttions mentioned in #130 (the issue you probably meant)
I enabled #ignore-gpu-blocklist
And the GPU acceleration works now, about:gpu does still show that some features are not enabled like WebGl2 but most of them are and work.

I'm still not sure if I should close this issue yet as there is definitely a bug in software rendering since 124, that can be mitigated by using hardware rendering which is of course better but still idk.
