I can confirm the bug, exact same behavior here. Upgraded from ubuntu 19.04 and same flickering effect.
* I open the Tweak tool window * I try to hover one of the left menu's items -> it flickers, I can not manage to click on a menu item sucessfully * If I resize the window (I have to make it larger so that the menu displays larger), then the menu works as expected and the flickering effect disappears - I have to do it everytime I launch the app, though. -- You received this bug notification because you are a member of Desktop Packages, 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] Status in gnome-tweaks package in Ubuntu: New Status in gtk+3.0 package in Ubuntu: New Status in mesa package in Ubuntu: New Status in mutter package in Ubuntu: New Bug description: the gnome-tweak-tool window keeps flickering abnormally. this might be a bug as i have seen somebody else mention the issue somewhere in the internet. i do have the screencast of the phenomenon i can send it to you for the review of the problem i am facing. i am on ubuntu 19.10 system installed via bootable usb. before i had interrupted network upgrade of the system which was recovered via grub recovery mode. since i thought the flickering was due to all this, i fresh installed the system via bootable usb. still the problem is persistent and its abnormal irrespective of the animation button turned on or off. --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu8 Architecture: amd64 CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 19.10 InstallationDate: Installed on 2019-10-26 (1 days ago) InstallationMedia: Ubuntu 19.10 "Eoan Ermine" - Release amd64 (20191017) Package: mutter PackageArchitecture: all ProcVersionSignature: Ubuntu 5.3.0-19.20-generic 5.3.1 Tags: wayland-session eoan Uname: Linux 5.3.0-19-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin lxd plugdev sambashare sudo _MarkForUpload: True To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-tweaks/+bug/1850103/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
