SOLVED: I found the fix for the gnome-tweak tool. In my case, it turns out the rapid flickering occurs when Animations is disabled in the GENERAL page of GNOME-tweak. Re-enabling Animations stopped the window flicker. There is another minor artifact -- the Close-Minimize-Maximize- Search icons disappear from the application bar when using "<" to return to the main menu. But they do reappear when further clicking on page links in the left menu. The page link menu and the page menus display separately now in independent windows -- and this was the initial behavior I remember before disabling Animations. -- 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
