I tested this in a fresh Ubuntu 22.04 VM with default settings, and the bug does not appear. (Ubuntu 22.04 uses Gnome 42 on Wayland in standard configuration)

I did some more testing: affected: KWin (X11) LXQt (X11) unaffected: KWin (Wayland) Gnome (Wayland) I compiled both rgbds and SameBoy from source.

Why does Wayland work if it's unaffected by the bug? Shouldn't it be the opposite?

Yes, I'm using a custom QtCurve style recently.

I don't remember exactly, but I probably had QupZilla open when I tweaked some things. Does it not like style changes while it's running?

It works in a new profile. What could be the issue here?

I set it to delete the cache on exit, but the problem persists.

Yes, cache, html5 content and cookies are all auto-deleted on exit.

I found the culprit. It happens when setting a Firefox User Agent. `Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:58.0) Gecko/20100101 Firefox/58.0` setting this string will cause the above bugzilla example...
