Whole-screen flickering on Bluefin-dx HX 370

Framework Laptop 13 Linux

I’m on Framework 13 with HX 370, and I wasn’t using any external monitors when I found this bug.

My whole screen flickers grey rapidly when I visit this page on Firefox and move my mouse about 1/3 of the way from the top left corner:

Possibly an upstream mesa bug? What do I do now? Can anyone else reproduce this and does anyone know any workarounds?

I’ve determined the issue doesn’t just happen on this one webpage.

When I pasted something in vim in a ptyxis distrobox, my external USB-C display turned off. How did this happen?

Things seem to have improved after I added kernel parameters amdgpu.dcdebugmask=0x12 amdgpu.sg_display=0 and set gfx.webrender.software=true in Firefox about:config. I also needed to set vsync mode to Disabled in Godot’s editor settings to keep the editor responsive while running a game. If I need to use further workarounds to get things running smoothly I may post them in this thread.
