I have the exact same issue as described by original report. Two windows of the browser on different workspaces, only happens when I use Wayland session. I collected more data on this:
Release: Ubuntu Noble Numbat 24.04 and Ubuntu Mantic Minotaur 23.10 Hardware: Dell Inspiron-16-Plus-7620, i7-12700H, 32GB RAM. Browsers tested: Vivaldi (deb), Brave (deb), Brave (snap), Chromium (snap) As suggested by @vanvugt , I switched one browser setting, and it immediately solved the issue for me on all browsers affected. chrome://flags/#ozone-platform-hint Changed from default (always use x11), to auto (try wayland first, fallback to x11). It is quite easy to check that the setting is applied, by running this on the browser: chrome://gpu/ Searching the text for "ozone" I can see the following: --ozone-platform-hint=auto --ozone-platform=wayland I hope this helps. Please let me know if further testing is required. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xwayland in Ubuntu. https://bugs.launchpad.net/bugs/1906792 Title: Chromium tabs freeze with two windows on Wayland (Xwayland) To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/1906792/+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
