Description PGillespie 2021-05-31 23:18:16 UTC
SUMMARY

After setting Right Center Edge to "Desktop Grid" via "Touchscreen Settings", and after invoking the Desktop Grid, the grid itself does not respond to touchscreen gestures like tapping, forcing the user to choose another desktop or app via the touchpad or mouse.

STEPS TO REPRODUCE
1. Set (in my use case) right center edge to "Desktop Grid" in Touchscreen Settings.
2. Invoke Desktop Grid via touchscreen.
3. Attempt to interact with the desktop grid via touchscreen.

OBSERVED RESULT

Desktop grid does not respond to touchscreen gestures.

EXPECTED RESULT

Yeah, it was working, but then broke again recently. See Bug 456133 which is tracking that. I'm going to work on it today.
