I believe I have this bug with my N4200 Acer swift laptop. I was convinced it was a hardware problem. Screen flashing (the picture gets stretched and repeated horizontally while flashing) when the mouse pointer is at certain positions in the screen. It is easily repeatable in Lubuntu 24.04 with the hwe kernel with the mouse just above the task bar on the right hand side. I spent the weekend looking for a new laptop, but before I parted with some money I thought I better double check there was not a cheaper solution!
Plugging in an external monitor to the hdmi port fixes the problem. As does forcing the hdmi port on with the laptop screen mirrored to that port. So that's another workaround. Reverting to a 6.5 kernel also fixes the problem. This led me to this bug report. If you haven't done that though, it is hard to find this bug. Surely this should be urgently fixed? I can't be the only one to be looking at buying new hardware unnecessarily? -- 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 in 6th-8th gen CPUs) on Linux 6.8 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/2062951/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
