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.
