Shift key combinations and Caps Lock not working inside Gamescope (Wayland + KDE, openSUSE)

[BASStardo23]

Is there an existing issue for this?

• I have searched the existing issues

Are you using any gamescope patches or a forked version of gamescope?

• The issue occurs on upstream gamescope without any modifications

Current Behavior

When running any game or application inside Gamescope on openSUSE, Wayland host session, KDE Plasma, the following keyboard issues occur:

1. Shift + key combinations do not register inside the Gamescope session.
   Example: Shift + W, Shift + A, Shift + any key fails inside the game, even though they work correctly on the host.

2. Caps Lock does not toggle uppercase inside Gamescope.
   The LED on the keyboard toggles, but the key state is ignored inside Gamescope clients.

Keyboard input works normally outside Gamescope.

These behaviors are present both in Steam titles and non-Steam applications.

This does not match any existing issue in the tracker. Issues such as #1693 (Super key stuck), #1902 (shortcuts failing on Wayland), and #1508 (layout vs hardware mapping) are related to keyboard handling, but none describe the complete loss of Shift combinations and Caps Lock state.

Steps To Reproduce

1. Start a Wayland session (KDE).

2. Launch any program via Gamescope:

gamescope -- kate

or via Steam:

gamescope -w 1440 -h 1080 -S stretch -f -r 239 --force-grab-cursor -- %command%

3. Attempt to type uppercase letters or use Shift-based input in a game/application.

4. Observe that Caps Lock and Shift modifiers do not apply inside Gamescope.

I can confirm the behavior. This happens to me as well.

[matte-schwartz]

hmm, haven't been able to reproduce this one with KDE 6.5.4 and gamescope 3.16.17 on Arch with gamescope -- konsole for Caps Lock or gamescope -- code --wait to test shortcuts,

are you using the Fedora-packaged version of gamescope? might be worth trying to compile gamescope yourself to see if it's an issue with the packaged version

[theholypumpkin]

I installed the package via zypper on openSUSE Tumbleweed. Maybe it a packaging issue and should be reported to the package maintainers at openSUSE instead
