Public bug reported:
I am experiencing screen glitches on the internal display of my Dell XPS
13 9340 laptop when using kernel version 6.8.0-38-generic on Ubuntu
24.04. The glitches are visible immediately from the login screen and
persist throughout the session.
Steps to reproduce:
1. Boot the system with kernel 6.8.0-38-generic
2. Observe screen glitches on the internal display
The issue is not present when:
1. Booting the system with kernel 6.8.0-31-generic
2. Using an external display (connected via HDMI through a USB-C adapter)
System information:
- Device: Dell XPS 13 9340
- GPU: Intel Arc Graphics (Meteor Lake-P)
- Driver: i915
I have tested multiple times by switching between kernels, and the results are
consistent:
- 6.8.0-38-generic: Glitches present
- 6.8.0-31-generic: No glitches
This suggests a regression in the kernel that affects the display driver
or GPU support for this specific hardware.
I can provide additional logs or perform further tests if required to
assist in resolving this issue.
