I have got news. I do not have this problem anymore on my whole system. Right now it is limited to the Telegram app (installed over flatpak).
I watched for this bug on other flatpak applications as well, such as Green with envy and discord, discord uses org.freedesktop.Platform/x86_64/19.08 as its runtime, as does Telegram. I was unable to observe this lagging on any other flatpak applicaton, however. Which theoretically is good news, because I can remember having this problem on discord as well. I updated telegram with the flatpak update command, but the problem did consist. Maybe a reboot might fix it at this point. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1875957 Title: Random freezes for 1 second To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-440/+bug/1875957/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
