Describe the Bug

Sunshine with capture method wlroots and software encoding (libx264) gives a black screen with horizontal lines in Moonlight.

Setting capture method to kms works fine.

I also tested both software encoding (libx264) and VAAPI (hevc_vaapi). Both fail with wlroots and both work with kms, so the issue appears to be related to the capture backend rather than the encoder.

Sunshine repeatedly logs:

-------- Start of Wayland monitor list --------
... snip ...
Error: [wayland] Frame capture failed

Sway logs:

00:09:48.184 [ERROR] [wlr] [EGL] command: eglCreateImageKHR, error: EGL_BAD_MATCH (0x3009), message: "createImageFromDmaBufs failed"
00:09:48.184 [ERROR] [wlr] [render/egl.c:818] eglCreateImageKHR failed

Environment:

• Sway 1.12
• Sunshine 2026.605.170308 (commit fa4fbbd)

Expected Behavior

sunshine to moonlight works fine.

Additional Context

• wayvnc works correctly on the same system.
• An older Sunshine version (2025.924.154138) also failed with wlroots, but additionally segfaulted when a Moonlight client connected.
• Updating the system and Sunshine to the latest release removed the segfault, but wlroots capture is still broken.
• i have an nvidia card. but it's set in draining mode. So it can't be used by anything.
