Weird white squares all over the place with latest version

This is likely due to using Qt 6. Unfortunately we cannot downgrade Linux back to 5 because we had upgraded our OpenSSL version to 3 in the mean time and Qt 5 insists on dlopening an OpenSSL 1 so which causes crashes when the two are in the same process.

I swear that we must be the only ones using QtWebEngine for anything other than the most simple of pages.

This appears to be only with NVIDIA GPUs on Linux. Does it make a difference if you use a different set of drivers? Which are you currently using?
