Hi, first to say: I've been testing Ubuntu-Budgie. There is no option to run on Wayland. So I downloaded (2021-02-02) and installed Ubuntu 21.04 Desktop to perform the test and found some surprising results: 1. fresh installation, running on Xorg: the flickering is clearly visible. In fact, the cursor flickers, if anywhere on the screen some redrawing happens. To reproduce: open Term. A slight flickering is visible whenever the console cursor is disappearing and reappearing. This is also the case outside the Term window. Increase the effect by launching Firefox and browse to cnn.com. While opening the page, a lot of redrawing is happening (the little bullet in the tab, some line in the bottom about loading, and the many items on the page. During the pay load, cursor is flickering anywhere on the screen. 2. logout and login, this time on Wayland: No such effect. 3. logout and login, again on Xorg, again no such effect!
Btw.: I cancelled to install updates to keep a stable environment, so just the version as indicated above. If you have any idea, how logging in on Wayland cured this effect (reinstalled two times to be sure), I might be able to check on Ubuntu- Budgie (where I can't simply select Wayland). -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1913963 Title: [Cherry Trail] [modeset] Cursor flickering on dual screen setup To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1913963/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
