Thank you very much for your quick reply. I should have looked into the logs...
Installed firmware-linux, and now the 100% CPU issue is gone.
Unfortunately, the flickering issue (more often on black screens) is still
present with kms, so for now I'm sticking with having it disabled.

If you want to have doing some debugging/testing/whatever, feel free to ask...

Best regards,
