Comment 37 for bug 2062951

I'm running Dell Latitude 7390 with Intel UHD Graphics 620 (8350U). So 8th Gen rather than 9th. I get occasional glitching, usually on battery power and when scrolling, and always when pointer is in the bottom right of screen. I did try the kernel params listed here (i915.enable_dc=0 intel_idle.max_cstate=2, intel_idle.max_cstate=4) and this did not resolve. I have used Debian 12 and Fedora 40 on the same hardware and did not observe this. The behaviour has occurred when using Firefox (snap), VSCode (deb), Chrome (deb) and . Its not super intrusive on my hardware but it is annoying.
