> Is this the same bug that is being discussed here?

No, because the problem here is specific to GTK 4 and has been around for years. That is, since you didn't have this problem with 2.40, this bug is not your bug.

You're probably hitting either bug #259644 or bug #261874, depending on whether or not you see those KMS DRM_IOCTL_MODE_CREATE_DUMB error messages. Please confirm.
