I upgraded from 32 to 33 a few nights ago, and the external monitor now flashes during screen updates when on Wayland. On X11, the output appears fine, but it is terribly slow to interact with - clicking on a line in VS Code involves a 5 second wait for the cursor to appear.
I have the Lenovo Legion 5 (4600H + Gtx1650) and I’m using the nouveau drivers. On 32 these performed flawlessly.
I also booted from a live USB with 33 on it - freshly downloaded. The same problem appeared, so I think it’s quite likely a regression/new issue with something 33 has introduced.
journalctl looks uninteresting, there don’t appear to be any major warnings or issues.
I’ve also attached a GIF demonstrating the issue
