I took video showing the bug being reproduced on 21.04. Unfortunately it's not the best. The video in the bug I linked above is clearer.
https://youtu.be/dSPUFTfpzZc ** Description changed: Steps to Reproduce: In the Settings applet choose Accessibility -> Zoom. Toggle the switch on. This happens whether or not you actually magnify the screen. When the mouse is moved anywhere on the screen, it leaves behind repeated partial square trails in its path. + + This is the same issue reported in: + https://bugs.launchpad.net/ubuntu/+source/meta-gnome3/+bug/1872870 ProblemType: Bug DistroRelease: Ubuntu 21.04 Package: gnome-shell 3.38.2-1ubuntu1 ProcVersionSignature: Ubuntu 5.8.0-36.40+21.04.1-generic 5.8.18 Uname: Linux 5.8.0-36-generic x86_64 NonfreeKernelModules: zfs zunicode zavl icp zcommon znvpair ApportVersion: 2.20.11-0ubuntu55 Architecture: amd64 CasperMD5CheckMismatches: ./casper/filesystem.squashfs CasperMD5CheckResult: skip CasperVersion: 1.456 Date: Sat Feb 27 00:06:13 2021 DisplayManager: gdm3 GsettingsChanges: - + LiveMediaBuild: Ubuntu 21.04 "Hirsute Hippo" - Alpha amd64 (20210123) ProcEnviron: - TERM=xterm-256color - PATH=(custom, no user) - LANG=en_US.UTF-8 - SHELL=/bin/bash + TERM=xterm-256color + PATH=(custom, no user) + LANG=en_US.UTF-8 + SHELL=/bin/bash RelatedPackageVersions: mutter-common 3.38.2-1ubuntu1 SourcePackage: gnome-shell UpgradeStatus: No upgrade log present (probably fresh install) -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1917103 Title: Accessibility: Zoom: Mouse pointer leaves square trails as it moves across the screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1917103/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
