Black artifacts on Windows Viewer when running 3D applications (RTX 5050, Windows 11)
Quote from Kronenbourg on 03/07/2026, 15:34Hello,
I would like to report a reproducible issue with spacedesk.
Host PC:
– Windows 11
– AMD Ryzen 5 5600
– NVIDIA GeForce RTX 5050
– NVIDIA Driver 610.62
– spacedesk Driver Package 2.2.25Viewer:
– Windows 11
– Lenovo laptop
– spacedesk Viewer for WindowsConnection:
– Both devices are connected to the same Gigabit Ethernet router.
– Both devices are using wired Ethernet (no Wi-Fi).Issue:
When the Host PC is idle or only running normal desktop applications, spacedesk works normally.However, as soon as I launch any GPU-accelerated 3D application (for example Blender or Elden Ring), the Viewer starts showing random black artifacts/flickering. Video playback (YouTube/Twitch) on the Viewer may also stutter while the 3D application is running.
The primary monitor connected directly to the RTX 5050 never shows any artifacts. The issue only appears on the spacedesk Viewer.
Additional information:
– GPU usage is usually below 15%.
– VRAM usage is low.
– CPU usage is normal.
– The issue does not seem to be related to GPU performance.I have already tried:
– Reinstalling spacedesk.
– Lowering the Viewer resolution.
– Lowering image quality.
– Software Encoding (MJPEG forced).
– Hardware Encoding.
– Ethernet connection instead of Wi-Fi.
– Disabling MPO.
– Chrome and Firefox.
– Different 3D applications (Blender, Elden Ring).
– Reinstalling the NVIDIA driver.Unfortunately, none of these changes solved the issue.
Could you please check whether this is a known compatibility issue with NVIDIA RTX 5050 or Driver 610.62? If necessary, I can also provide diagnostics logs or a video demonstrating the problem.
Thank you.
