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.

I see this same behavior when testing the latest master branch on Sway (I selected to autodetect the catpure method, and also tried selecting wlroots directly).

When starting Sunshine, for some reason it seems to trigger my screen capture program (slurp + swappy, which I have bound to the PrintScreen input), which I have to dismiss. Then when connecting from a client (I tested from Android) I get the same black screen with glitchy horizontal lines shown on the client. I can enable mouse control and move the mouse around on the host from the client, but the video remains glitched.

Switching capture method back to KMS works as expected.

If it would be helpful I can try again and attach logs.

I'm also seeing this issue,
I jumped to pre-release to try some of the changes that enable the vulkan wlroots renderer and headless backend which gives the error
[wlr] [render/vulkan/texture.c:545] Number of planes (1) does not match format (2)
on this pre-release build (on every encoder type)

and with WLR_RENDERER=GLES I get the same as @navneetankur
[wlr] [EGL] command: eglCreateImageKHR, error: EGL_BAD_MATCH (0x3009), message: "createImageFromDmaBufs failed"
[wlr] [render/egl.c:818] eglCreateImageKHR failed

This is using stable sway, wlroots19, and mesa packages on an AMD 7900XT (RADV NAVI31)
