Flickering since one week

[thierryroncalli]

I have a DELL XPS 13 9340 (New Version) and I have installed Ubuntu 22.04. One week ago, I notice some screen flickering (horizontal colored lines appear when moving the mouse).
I have reformated the hard drive and installed a dual boot Windows & Ubuntu (in order to check the issue with Windows). The problem disappears. But today fllickering appears again when using Ubuntu. I have no problem with Windows. If I boot my computer with the Ubuntu USB key, the problem disappears.
I suspect that an update version of Ubuntu is installed and produces this flickering.
Many thanks for your help.

Had the same issue on my XPS 13 9340 with Ubuntu 24.04 (kernel 6.8.0-41-generic).
The issue is fixed by upgrading to the oem kernel:
sudo apt install linux-oem-24.04
The fix is planned to be fixed in "6.8.0-45.45 or later".
