Describe the bug

Disclaimer: I've compiled this bug report with the help of ChatGPT.

For some weeks I am experiencing reproducible black screen freezes on KDE Plasma 6 (Wayland) when using the NVIDIA Open Kernel Module driver.

The problem manifests in two closely related failure modes:

Hard GPU error with Xid 69 in kwin_wayland

Silent rendering failure with GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT

Both result in a complete black screen while the system remains running.

The issue is triggered by GPU-accelerated workloads such as Darktable (OpenCL/EGL heavy usage) and Firefox (WebRender / tab creation).

Failure Mode 1 – Xid 69 / EGL context collapse (Darktable)

This failure occurred during GPU-heavy usage in Darktable.

Relevant kernel and compositor logs:

NVRM: Xid (PCI:0000:2b:00): 69, pid=1256, name=kwin_wayland, Class Error: channel 0x00000057, Class 0000c797, Offset 00000d40, Data 00000001, ErrorCode 00000004

Followed immediately by complete EGL / QRhi context collapse in KWin:

kwin_wayland: QRhiGles2: Context is lost
kwin_wayland: Failed to create RHI (backend 2)
kwin_wayland: QQuickRenderControl: Failed to initialize QRhi
kwin_wayland: Could not make egl context current! EGL_BAD_CONTEXT
kwin_wayland: EglGbmLayerSurface::renderTestBuffer: failed to make opengl context current
kwin_wayland: Could not delete framebuffer because no context is current
kwin_wayland: Could not delete texture because no context is current

After this, the screen turned permanently black and the session became unusable.

Failure Mode 2 – Silent framebuffer failure (Firefox)

More recent occurrences happen without Xid, when opening a new Firefox tab or switching tabs.

Only error observed:

kwin_wayland: Invalid framebuffer status: "GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT"

After this message, the entire screen turns black.
No Xid, no GPU hang, no timeout messages are logged.

To Reproduce

Boot into Plasma 6 Wayland session

Use NVIDIA Open Kernel Module driver 590.48.01

Trigger GPU-accelerated workload:

Open Darktable and work with images

Or open Firefox and create / switch tabs
