Describe the problem

It works fine when using Xorg(with WaylandEnable=false), but when using Wayland, some windows work, some not.
For example, Chrome works, gnome-terminal not.

Source code / logs

No any debug log when trying to scroll on windows that do not work, and normal logs for those work fine.

Thanks for reporting the issue! It seems that some users reported similar issue before.

The main logic of the extension is: press hotkey -> create an overlay -> detect scroll event from this overlay -> change transparency based on scroll event.

Are you able to see the log such as [DEBUG][TransparentWindow] Hot key pressed? If there is such log, we can confirm hotkey detection works fine.

[OmmyZhang]

For the windows that work, yes there're such logs.

$ journalctl /usr/bin/gnome-shell -f
...
...
Jun 23 14:54:53 D gnome-shell[1121]: [DEBUG][TransparentWindow] Hot key pressed
Jun 23 14:54:53 D gnome-shell[1121]: [DEBUG][TransparentWindow] 8
Jun 23 14:54:53 D gnome-shell[1121]: [DEBUG][TransparentWindow] Modifier key pressed, listening to scroll
Jun 23 14:54:53 D gnome-shell[1121]: [DEBUG][TransparentWindow] overlay created
Jun 23 14:54:53 D gnome-shell[1121]: [DEBUG][TransparentWindow] Hot key pressed
Jun 23 14:54:53 D gnome-shell[1121]: [DEBUG][TransparentWindow] 0
Jun 23 14:54:53 D gnome-shell[1121]: [DEBUG][TransparentWindow] overlay destroyed

But for those not work, just nothing. No any log appears after I press alt.

The hotkey logic is defined in a per-display way:

gnome-shell-extension-transparent-window/extension.js

Line 161 in cc9bc70

sig_keymap = keymap.connect('state_changed', onHotkeyPressed);

I'm not sure whether it is possible that wayland uses different displays for different windows.

Could you list all window types that don't work? This may give us some hint.
Also please check whether it is possible the hotkey is masked by application's shortcut key.

[OmmyZhang]

Not work: gnome-terminal, Files, Settings(and all system setting windows, such as Extensions and Tweaks), gedit.

It seems only work on applications that are somehow third part, like Firefox, Chrome, VLC.

As there's no any log when I just press alt, I think this problem may not related to application's shortcut key.

[pbxqdown]

for the gnome-terminal window, do you select/focus that window and hotkey doesn't work? how about try this: select a chrome window, press hotkey, then move cursor to hover on gnome-terminal window, then scroll and see if it changes opacity.

[OmmyZhang]

select a chrome window, press hotkey, then move cursor to hover on gnome-terminal window, then scroll and see if it changes opacity.

Yes, this works. Terminal's opacity is changed. Amazing!

[pbxqdown]

Awesome! But still this is strange..guess gnome-terminal somewhat capture the hotkey event such that it can not be received.
