Symptoms

When playing SKALD via Proton, holding the "Shift" key (used to highlight interactive objects)
the highlight "rapidly flicker on and off" instead of remaining stable.

This behaviour suggests that the game may be receiving repeated press/release events
while the key is physically held down.

Reproduction

1. Launch SKALD via Steam using Proton
2. Load into the game world
3. Press and hold the "Shift" key to highlight objects
4. Observe object highlights

Additional Observations

• The issue is reproducible 100% of the time
• Does not appear to be caused by keyboard hardware (no key repeat issues outside the game)
• This also happens on GE-Proton, and stable Proton 9 or 10.
