I've tried a few things to try to narrow this down as best I can. What I know. When it happens, it looks like the window has no background, and just duplicates what is behind it, if I move the window around, I see visual artifacts. It only happens sometimes, but once it happens only closing and reopening the browser can fix it. Once it loads and it is good, it's good until I close it again. It can happen on the profile select screen too. If I set `gfx.webrender.software` or `layers.acceleration.disabled` to true, or set an env `export MOZ_ACCELERATED=0` the issue goes away. Info about my system. I primarily use nightly or locally built Firefox's. I'm using Fedora 34, I have an nvidia gpu, using X11, and Gnome 40.5. The laptop is a Razer Blade 15 Advanced Model - QHD 240Hz - GeForce RTX 3080
