--- Comment #1 from Simon Schmeisser <mail_to_...@gmx.de> --- I attached an external monitor, opened the screen settings, toggled the laptop screen off and on and it was completely normal again. Let's see for how long. But this makes me doubt it is an hardware issue (besides that it started with the last update) -- You are receiving this mail because: You are watching all bug changes.
