Thanks. I wonder if this bug is directly related to "using Intel graphics on my hybrid Nvidia laptop". Since regular Intel GPU users never seem to see such problems. Although this is also one of the first bug reports about a Coffee Lake GPU I have seen too, so it might be an Intel problem...
1. Can you please try disabling the Nvidia ("discrete") GPU in the system BIOS and tell us if that fixes it? 2. Can you please also run 'dpkg -l > allpackages.txt' and send us the resulting file 'allpackages.txt'? 3. If the problem persists (and only if) then please also attach copies of your Xorg log files (/var/log/Xorg*log). Please also attach a copy of your Xorg configuration file if you have one (find /etc -name xorg.conf). -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to totem in Ubuntu. https://bugs.launchpad.net/bugs/1811808 Title: Tearing and/or flickering when using Intel graphics To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/totem/+bug/1811808/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
