Thanks. Next I would like to confirm if this is really a pure Intel bug. Just for testing, can you please try uninstalling the Nvidia driver, reboot and then log into "Ubuntu on Wayland"?
Does using a Wayland session avoid the bug? Please also run 'xrandr' in the Wayland session and send us the output. ** Tags added: hybrid ** Also affects: gnome-shell (Ubuntu) Importance: Undecided Status: New ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to totem in Ubuntu. https://bugs.launchpad.net/bugs/1811808 Title: Tearing and/or flickering when using Intel graphics Status in gnome-shell package in Ubuntu: Incomplete Status in totem package in Ubuntu: Incomplete Bug description: When using Intel graphics on my hybrid Nvidia laptop, videos in Totem have awful tearing/flickering which makes them essentially unwatchable. With default X settings, I get tearing across the top of the screen (but I also get very noticeable tearing in other applications); if I enable TearFree (which eliminates tearing in Chrome), the tearing turns into jagged black flickers which extend from the top of the screen right down to near the bottom of the screen on some frames. The flickers are visible in screenshots, so I have attached one.
