Description nanority 2024-11-17 17:21:52 UTC

After installing F41 from the live image over a previously installed F39 instance my main screen (32", 1440p) connected to an Intel A750 is corrupted/distorted. This manifests as every other line of pixels displaced by about 5mm to the side. The problem does not exist on a secondary screen connected to the onboard graphics.
This bug exists while installing F41 from the live image as well as booting the system after install.

I can exclude any hardware error, as the screen works fine under Windows as well as during bootup. The start screen during bootup is displayed correctly right until the gnome login screen appears. The error continues to be present even after the login. Interestingly, even at this stage, the mouse pointer is not affected by the error under all circumstances. I also verified that the screen corruption is not connected to screen orientation, resolution, scaling or refresh rate. The bug also does not show up in screenshots, therefore I attached a photo of the error on screen as example.

I have been looking around log files to identify error messages or warnings possibly connected to the problem but have not been successful so far. Therefore, I am not certain gnome-shell is package of origin for the bug.

For general information I will attach the output of 'fpaste --sysinfo --printonly' as well as 'inxi -Fzxx'. If further data is needed, I'm going to happily provide answers to all request but can not promise to reply the very same day every day.

Thanks a lot!

Reproducible: Always

Steps to Reproduce:
1. Bootup to gnome login screen

Actual Results:
Screen connected to Intel A750 is corrupted/distorted.

Expected Results:
Normal display of gnome login screen and desktop after login.

This component is maintained by the GNOME project. Issues with it should be reported directly to GNOME at https://gitlab.gnome.org/GNOME/.

This issue should only be kept open if it:

1. Relates to Fedora packaging or integration with other Fedora components
2. Is required for Fedora release processes, such as blocker bugs and freeze exceptions

If this issue isn't needed for either of these two reasons, please:

 * create an issue with GNOME
 * add a link to the GNOME issue here
 * close this issue as CLOSED/UPSTREAM

Thank you!
