If you've encountered those unsettling yellow or green lines crawling across your Steam Deck OLED screen, take a deep breath—you're experiencing a known software issue, not a hardware failure.
Understanding the Display Issue
These mysterious lines typically appear during transitions between desktop and gaming modes, moving slowly from right to left across your display. While alarming at first glance, this visual glitch has a straightforward explanation and solution.
The Technical Reality
Valve engineers have confirmed this issue stems from display signal chain disruption during mode switching. The display controller occasionally fails to recover properly when transitioning between different video modes, creating these temporary visual artifacts.
Key point: This is definitively a software-related problem, not hardware damage.
The Reliable Solution
Resolving this issue requires a simple system restart:
- Hold the power button for approximately 10 seconds to force complete shutdown
- Press the power button to restart your device
- Normal display function will be restored immediately
This hard reset clears the display signal confusion and eliminates the line artifacts every time.
Distinguishing Real Hardware Issues
Contact Valve support if you experience:
- Persistent display problems unresolved by reboots
- Dead pixels or permanent screen defects
- Consistent hardware-related visual anomalies
However, the specific moving line issue is a documented software quirk with a proven resolution method.
