Hi! I'm sorry I was unclear. I meant that I was on just "Ubuntu" and then switched to "Ubuntu on Wayland". Sadly this didn't help, so I created the bug report. Today I tried installing Ubuntu in Legacy mode. This didn't help. Again, the graphic safe installer works normally but not the normal installer. How shall we continue debugging?

Public bug reported: The screen on my HP AIO computer flickers. I'm able to browse the computer, but it's giving me headache. Flickering consists pattern of 2cm height white vertical pixel lines (1*Wpx white and 1*Wpx transparent lines) and 2cm transparent section. Flicker also has 1px lines with dashes ending them about 10cm from left of the screen and 2cm from right of the screen. Mathematically letter W being 100% of screen width in above description. Flickering seems to be consistent to screen refresh state (~60Hz). Changing refresh rate does not affect in to amount of flickering. Same thing not happening in Windows nor BIOS. Even though this looks a LOT like a hardware/wiring issue. Also the problem is visible in Ubuntu installer, but not in graphic safe one.
