I’m using a DisplayLink dock (USB-C) with two external monitors on Windows 11. Driver is the latest one from the DisplayLink site. Normal desktop use, browser, and Office are fine.
The issue only appears when I open some lighter apps in the background — for example a small browser game tab (I’ve been testing with simple oops games in Chrome) or similar low-load fullscreen/windowed content. Every so often one of the external displays goes black for 2–3 seconds, then comes back. The laptop screen stays on the whole time.
It doesn’t seem to happen with video playback or heavier programs, only with these lighter windowed apps. I’ve already tried:

Clean reinstall of the DisplayLink driver
Different USB-C ports and cable
Disabling hardware acceleration in the browser

Has anyone seen display dropouts tied to specific light apps rather than high GPU load? Any known workaround or setting worth checking?
