I believe I have found a merge request related to the bug upstream: https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/4686
If you look at the referencing issues, both the automated shortcut and sticky keys issues might be fixed by this merge request. Furthermore, it is interesting to note that an issue related to poor CapsLock behavior in Xwayland applications is also referencing this merge request. I can confirm I have inconsistent CapsLock responses in questing. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/2125240 Title: Modifier key state changes ignored if too fast Status in mutter package in Ubuntu: New Bug description: Ubuntu 25.10 Mutter 49~rc-0ubuntu2 Wayland Regression from plucky resulting in instant keyboard shortcuts being handled out of order. For example, if the evtest sequence shows: Shift down Syn ... seconds later A down Syn Shift up Syn ... A up Syn where the A down, Syn, Shift up, Syn events occur within < 1-5 ms of each other, the modifier is handled before the A, causing lowercase A to be pressed. Adding a 5 ms delay between those events fixes the issue. Similiar issue with (untested) fix for Mutter 49: https://gitlab.gnome.org/GNOME/mutter/-/issues/4315 (It appears this is not the fix as mutter 49.0-2ubuntu1 does not fix the issue.) Expectation: Order of key release events respected, so automated shortcuts work. Problem: With keyd or another input remapper via evdev/uinput, if modifier is released < 1-5 ms after the key in a shortcut, mutter reads the event as if no modifier was pressed. Similarly, with sticky keys enabled in Settings, sometimes a modifier that's latched will be lost on the press of the key. (When I refer to the key, I am referring to the final key in a shortcut, i.e., A in Shift+A) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2125240/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
