It affect me as well. I have Intel(R) UHD Graphics (CML GT2) and using i915 driver.
Added below lines to grub: i915.enable_dc=0 intel_idle.max_cstate=2 No luck. Then changed it to: i915.enable_dc=0 intel_idle.max_cstate=4 as per some suggestions Also no luck. I experienced the issue a few years back. Can't remember the Ubuntu version then. After adding above lines it was OK. Then after a kernel update it was all fine even without adding the above lines. Now, after upgrading to 24.04 the problem came back. It happens randomly for a coupe of seconds every an hour or so. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2062951 Title: Random flickering with Intel i915 (Gen9 GPUs) on Linux 6.8 (Ubuntu 24.04) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2062951/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
