Thanks. You mention that this only began once you rebooted into the 6.11 HWE kernel. Are you on Noble? Do you know the most recent kernel version before you started experiencing this issue?

Unplugging/replugging the monitor, or rebooting, sometimes (in about 1 out of 4 cases) fixes the problem. Note the monitor seems to be detected, because my desktop is extended into that (now invisible) region and windows placed on that extended desktop.
