--- Comment #11 from [email protected] --- Hi! I hope I've found what triggers this bug. In the display settings, there's a checkbox that enables controlling the hardware brightness with DDC/CI. When the bug was occurring, it was checked. I've unchecked it now and it's finally stopped causing this issue. I've attached a screenshot. -- You are receiving this mail because: You are watching all bug changes.
