Bug

Description

Hyprland crashed when attempting to share a single window via: https://mozilla.github.io/webrtc-landing/gum_test.html. Full screen share works.

How to reproduce

1. Go to https://mozilla.github.io/webrtc-landing/gum_test.html
2. Click Screen capture
3. Click Allow
4. In the popup select the Window tab
5. Pick any open window (in my case it was the terminal (alacritty))

Hyprland crashes.

I followed the guide: https://wiki.hyprland.org/Useful-Utilities/Hyprland-desktop-portal/

Looks like the error is here:

#6  drmFormatToGL(unsigned int) (drm=Python Exception <class 'gdb.MemoryError'>: Cannot access memory at address 0x2bc

[Ghosthree3]

Probably this, https://github.com/hyprwm/Hyprland/issues/4043 Which was fixed one commit after the 0.33.0 release, https://github.com/hyprwm/Hyprland/commit/83248b6936c00ddef6a39fa31a37949ca1a34ffe

[freddiehaddad]

I'll try to build/install from AUR and grab latest git.. TY!

[freddiehaddad]

Confirmed. That commit fixed it!
