Describe the Bug

Summary

With capture = kms on KDE Plasma Wayland, if the captured output's Color accuracy setting (KWin per-output colorPowerTradeoff) is set to "Prefer efficiency", Sunshine produces corrupted frames in the stream and intermittently crashes with SIGSEGV mid-stream. Setting the output to "Prefer color accuracy" fully resolves both. The failure is codec-independent (identical crash stacks on hevc_vaapi and h264_vaapi) and reproduces with a single settings toggle.

In KWin's efficiency mode, color operations are offloaded to the display driver's plane/scanout pipeline ("Preferring color accuracy limits potentially inaccurate offloading of color operations to the display driver" — KDE's own tooltip). The scanout configuration this produces on Intel appears to be something Sunshine's KMS grabber / EGL dmabuf import does not handle.

Expected Behavior

Stream renders correctly (or capture fails gracefully) regardless of the output's color/power tradeoff setting.

Additional Context

Environment

Component	Version
Sunshine	stable 2026.516.143833 (commit 14ffa6fd) AND beta 2026.703.144423 (commit 92a92306) — frame corruption reproduced on both; SIGSEGVs captured on stable (beta test window was short; corruption identical)
OS	CachyOS (Arch), kernel 7.1.2-3-cachyos
Desktop	KDE Plasma 6.7.2, Wayland (kwin 6.7.2)
GPU (capture+encode)	Intel Raptor Lake-S UHD (i915), VAAPI via intel-media-driver (iHD) 26.1.5, Mesa 26.1.4, libva 2.23.0
GPU (unused for streaming)	NVIDIA RTX 4090 Laptop (PRIME offload, driver 610.43.02) — hybrid laptop, panel on the iGPU
Display	eDP-1, 2560x1600@240 (DSC), 8-bit SDR panel
Sunshine config	capture = kms, encoder = vaapi, adapter_name = /dev/dri/renderD129 (iGPU render node)
Client	Moonlight, over WAN (zerotier)

Bug persists across: Sunshine stable 2026.516 → beta 2026.703, KWin 6.7.0 → 6.7.2, Mesa 26.1.2 (two build epochs) → 26.1.4, kernels 7.0.12 → 7.1.2.

Regression timing: the Sunshine binary (2026.516, installed 2026-05-19) streamed crash-free for a month — with PreferEfficiency as the standing default. Its first-ever coredump occurred 2026-06-20 16:53 — the same hour the system upgraded Plasma/KWin 6.6.5 → 6.7.0 (package log verified; no Sunshine change in that batch or that month). The KWin option and its documented behavior are unchanged across those versions; what changed is the implementation: KWin 6.7 re-enabled and rewrote its per-DRM-plane color pipeline programming (kwin!6600, kwin!8475 — rewritten pipeline-matching algorithm, 3D LUT support). In efficiency mode this now programs color ops into scanout planes on i915 — the same subsystem that required AMD/NVIDIA banding workarounds in 6.7.1. Sunshine's KMS import path mishandles the resulting plane/scanout state.

Steps to reproduce

1. Plasma Wayland session on an Intel(+hybrid) laptop; Sunshine with capture = kms, encoder = vaapi on the iGPU.
2. System Settings → Display & Monitor → set the captured output's Color accuracy to "Prefer efficiency"
   (or: kscreen-doctor output.eDP-1.colorPowerTradeoff.preferEfficiency).
3. Connect a Moonlight client and stream the desktop.
4. Generate window activity on the host (e.g. scroll a page in Chrome).

Observed

• Stream-side frame corruption: regions of the captured image break — e.g. the Plasma panel/taskbar renders black while a window is scrolling; some windows render fully invisible in the stream. The physical display is unaffected; corruption is only in the captured/encoded output.
• Intermittent SIGSEGV in sunshine mid-stream (observed between ~80 s and ~40 min in). With systemd Restart=on-failure this presents as a disconnect/reconnect loop.

Crashing thread (stripped binary, offsets stable across all crashes — 4 crashes over 2 weeks, 2 codecs):

#0  sunshine + 0x44adbe
#1  sunshine + 0x3fa1a4
#2  sunshine + 0x3fa3e7
#3  sunshine + 0x2853e0
#4  sunshine + 0x27e4b4
#5  sunshine + 0x13588f4   (std::thread trampoline)
#6/7 libc start_thread/clone

At crash time, threads for Mesa gallium VAAPI, PulseAudio capture (pa_simple_read), and the network epoll loops are all idle/waiting — the faulting thread is a per-session capture/encode worker.

Start with the KMS grabber and EGL dmabuf import path described in the report, using the Intel i915 setup and KWin "Prefer efficiency" mode to reproduce the failure. Compare capture behavior with the output set to "Prefer color accuracy" and test both h264_vaapi and hevc_vaapi. Done means frames remain intact and the capture worker does not crash during streaming.
