Latest gnome update breaks my fullscreen capability

Hello everyone!

I recently pulled like 5 days worth of updates in PopOS, and it seems a package upgraded called “mutter” which breaks all accelerated 3D fullscreen functionality. Notable broken games include but are not limited to TF2, CS:GO, City Skylines, Undertale, and basically any other game that requires 3D acceleration. Is there a way to revert this upgrade to restore my old mutter package?

Thanks for your help!

I also need to set layers.acceleration.force-enabled to true in Firefox and I do have h264 codecs installed and h264ify extension enabled, though I’m not sure if the latter contributes to smooth video playback.
