I can also confirm that I experience this issue. Before, I used Ubuntu 21.04 with Wayland, similar hardware/settings and the corresponding kernel of 21.04 and never had this issue once. After a fresh install of 22.04 it came up around once per hour.
When running "dmesg -T", the occurrence of the issue corresponds with error: [Fri Apr 29 13:10:21 2022] i915 0000:00:02.0: [drm] *ERROR* CPU pipe A FIFO underrun I tried to set: intel_idle.max_cstate=4 i915.enable_psr=0 It probably reduces the frequency the issue comes up but does not fix it. sudo lshw -c video *-display description: VGA compatible controller product: Skylake GT2 [HD Graphics 520] vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 logical name: /dev/fb0 version: 07 width: 64 bits clock: 33MHz capabilities: pciexpress msi pm vga_controller bus_master cap_list rom fb configuration: depth=32 driver=i915 latency=0 resolution=2560,1440 resources: irq:130 memory:e0000000-e0ffffff memory:c0000000-dfffffff ioport:e000(size=64) memory:c0000-dffff -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1970426 Title: screen suddenly starts flickering after update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1970426/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
