I encountered the same issue. I was planning to reinstall OS as restarting/shuting down/reinstall application did not help. This issue started happening after changing placement left to right in window titlebars. If the placement is changed from left to right/right to left, the flickering is appearing and menus in gnome tweak box are not registering/clickable. So, above solution worked for me. Resize the gnome tweak then change the placement setting then close it. Everything should be normal after that as long as you do not touch/move the settings of placement . Thanks, Xavier (xavierl) for solution. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to gtk+3.0 in Ubuntu. https://bugs.launchpad.net/bugs/1850103 Title: gnome-tweak-tool window keeps flickering on cursor hovering Status in gnome-tweaks package in Ubuntu: Confirmed Status in gtk+3.0 package in Ubuntu: Confirmed 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/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
