Black Screen When Screen Sharing on Hyprland: A Three-Bug Hunt

Sat, 27 Jun 2026 00:00:00 +0000

I couldn’t screen share. In Zen (a Firefox-family browser), picking Entire Screen in a Google Meet / browser meeting gave a perfectly black rectangle. The kicker: it failed the exact same way on two completely different machines — a desktop with an NVIDIA card and a laptop with a Radeon 680M. Same black screen.

That detail is the whole story, so I’ll spoil it up front: it was never the GPU. It turned out to be three separate bugs stacked on top of each other, each one independently capable of producing a black frame. Fixing any one of them still left it black, which is exactly why it was so maddening. Here’s the hunt.
