Description plumlis 2025-09-26 02:17:26 UTC
On a Wayland session, using the touchscreen to interact with GNOME Shell’s QuickMenu sliders (volume or brightness) causes the entire system to become unresponsive. The mouse pointer can still move, but clicks, keyboard input, and touch input do not work. The only options are to force shutdown or close the lid to suspend.

---------------

And it seems already fixed,Maybe need a new build?
https://gitlab.gnome.org/GNOME/gnome-shell/-/commit/e54aa588c1604b63e2f051e20c1ecb3e601beb5c

Reproducible: Always

Steps to Reproduce:
1,Disable all GNOME Shell extensions and log in.
2,Open the QuickMenu by tapping the top-right corner with the touchscreen.
3,Tap the volume or brightness slider (no need to drag, just a simple tap).
4,The system immediately freezes: keyboard, mouse clicks, and touch input stop responding, although the mouse pointer can still move.
Actual Results:
The system becomes completely unresponsive,but system is still runing. Only a forced shutdown or lid-close suspension is possible.

Expected Results:
Tapping or dragging the sliders should adjust the volume or brightness normally without freezing the system.

Additional Information:
Fedora 43
Wayland
GNOME Shell: 49.0
Mutter: 49.0
Devices tested: Lenovo Chromebook with touchscreen, Surface Go 2; both show the same issue when using the touchscreen.

Comment 1 Fedora Blocker Bugs Application 2025-10-11 11:14:26 UTC
Proposed as a Blocker for 43-final by Fedora user jonha using the blocker tracking app because:

 All elements of the default panel (or equivalent) configuration in all release-blocking desktops must function correctly in typical use.

Touchscreen use is probably typical enough.

Comment 2 Lukas Ruzicka 2025-10-13 18:35:27 UTC
AGREED AcceptedFinalBlocker

Discussed at the 2025-10-13 (blocker / freeze exception) review meeting:

This violates "All elements of the default panel (or equivalent) configuration in all release-blocking desktops must function correctly in typical use." for users with a touchscreen.
