@brion @yuvipanda @mattl @mirabilos Yeah, bug shows that, I wonder how it was for modern environments though, like I guess Windows Vista and later, and MacOS Jaguar? and later.
And I don't remember it in Wayland but I use a tiling compositor so much harder to notice and since I got my WebKitGTK-based browser in 2019, Firefox ended up being a browser only for things like WebRTC.
