Icons from the desktop flash through the browser, windows top bar gets distorted, all sort of glitches appear, parts of characters are missing in terminal, scrolling is inconsistent and the whole desktop becomes unusable. Under wayland the graphics are a bit more stable, but lots of glitches appear anyway, video reproduction in browser is stuttering and wobbly. Booting with previous kernel 5.8.0-48 seems to fix the issues. 5.8.0-50 is broken as well. this is the result of 'sudo lshw -c video' on my hp Elitebook 8470: *-display description: VGA compatible controller product: 3rd Gen Core processor Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 09 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:33 memory:d4000000-d43fffff memory:c0000000-cfffffff ioport:4000(size=64) memory:c0000-dffff To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1924624/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
