Mismatched input on wayland (with the environment variable QT_QPA_PLATFORM set to xcb)

[Vlusky]

Wrong part of the overlay gets highlighted whenever certain keys are pressed. Running it under wayland directly straight up doesn't work. Changing the QT_QPA_PLATFORM variable works for all the keys except anything beyond the right Ctrl key (so arrow keys, Insert, Home, ScrLk, Numpad, etc.)

To Reproduce

• Open a wayland environment (I'm using KDE Plasma)
• Open the terminal and run QT_QPA_PLATFORM=xcb obs
• Load a preset with any preset that displays the keypad (I'm using "qwerty-pixel-with-keypad")
• Press any key in that Navigation Keys area

Expected behavior

• The right arrow key should highlight the right arrow key part of the image.

Actual Behavior
Pressing Right Arrow Key or Pause Break results in this:

Additional information:

• Plugin version 5.0.6-HEAD-c99a526 build on 2024.10.24 17:24, installed from the AUR binary

Additional context
I tried changing the .json ID with the value I saw with evtest and double checking it with io-cct to no avail. I'm wondering if there's any better workaround to get these working since I know wayland reaaaalllyy hates these things.

The keyboard and mouse hook don't work under Wayland. See kwhat/libuiohook#196

Is there any light at the end of the tunnel for using input-overlay on wayland?
I'm using a special input device replacing the keyboard (but still being recognized as a keyboad) and would like to show its input. It has an extension (also recognized as a keyboard) and I'm sometimes even hitting keys on the normal keyboard as well. Here I'm suffering from a freeze issue when switching between HID devices using X11: https://gitlab.gnome.org/GNOME/mutter/-/issues/398#note_2423890

I don't know. Here's kwhat's words though:

i think what got me was it almost worked by tricking OBS into running in X11 mode. almost every other key got highlighted correctly.

i might have to search for some other solution for highlighting inputs. if all else fails i just gotta figure out how to roll back to X11 Plasma.

I mean from what I can tell keyboard input maybe kinda somewhat works but mouse input does not but until there's support for it in libuiohook there's not much I can do.

[Corben78]

Personally it would be enough to see keypresses. I had shown mouse clicks too, but the position of the mouse cursor was never used. And if the mouse buttons are missing or not, I can live with that. If it's possible to visualize keypresses again, that would be totally great!

[univrsal]

That's ultimately up to kwhat. I don't really have time to work on libuiohook.

Run obs under x11 it will work
env QT_QPA_PLATFORM=xcb obs
