Could you create a new profile to perform a test?
For example, there is a new profile called `desktop_test`.
Please set the preference `gfx.webrender.debug.dl.dump-parent` to true.
After setting it, close Firefox. Run following command to collect display list dump.
```
timeout 10s firefox -P desktop_test > dl.log 2>&1
```
Wait for 10 seconds! It will close automatically. Please attach `dl.log` here.
Display list is about what was drew on layers. Hope this can help to identify if this is graphics (GPU) issue or a rendering issue (or even earlier).
