it was in default desktop session when i freshly installed it. when i realized the problem, i decided to download gnome-vanilla-desktop with the hope that problem won't transfer in different desktop environment and only with no luck.
i had been using 18.10 and 19.04 in the same device earlier where i did not have such issues regarding graphics transition. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1850103 Title: gnome-tweak-tool window keeps flickering on cursor hovering [Intel Penryn: Core 2 T6600] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-tweaks/+bug/1850103/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
