Two-finger tap on SSD title bar does not produce context menu
I'm seeing the following behaviour under Xorg:
- Open an app that uses SSD, e.g. Alacritty
- two-finger tap on the title bar with a laptop trackpad to open the window context menu
The result is no context menu, the two-finger tap is ignored. However I do see the cursor of Alacritty blink indicating a momentary loss of focus, so there is something happening.
If you immediately do a two-finger tap again, without moving the mouse cursor, then the context menu does appear. However, the first two-finger tap after any cursor movement does not result in a context menu.
Interestingly, if I use the click area of my laptop trackpad to right click, the context menu does appear. It's only a two-finger tap that shows the issue.
I'm using Arch Linux, with mutter built from 8fd55fef (second most recent commit in master)
Could potentially be a libinput problem, but since mutter has updated more recently I thought of it first.
libinput debug-events --enable-tap
Shows the right click events even when the context menu does not appear, making it seem less likely to be a libinput problem.
