Package: kwin-x11 Version: 4:5.13.1-1 Severity: important Dear Maintainer,
kwin frequently terminates without crash dialog on my system. It happens in various situations, most often when switching virtual desktops. Every version I have tried from Buster so far was affected, only solution is to downgrade kwin-x11 to version from Stretch (4:5.8.6-1). Versions of kwin-x11 I have tested so far: 4:5.10.5-2 4:5.12.1-1 4:5.13.1-1 When I run kwin from terminal window, I see following output: =========================================== $ kwin QXcbConnection: XCB error: 3 (BadWindow), sequence: 172, resource id: 44040198, major code: 20 (GetProperty), minor code: 0 OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: GeForce GTX 970/PCIe/SSE2 OpenGL version string: 3.1.0 NVIDIA 390.67 OpenGL shading language version string: 1.40 NVIDIA via Cg compiler Driver: NVIDIA Driver version: 390.67 GPU class: Unknown OpenGL version: 3.1 GLSL version: 1.40 X server version: 1.19.6 Linux kernel version: 4.16 Requires strict binding: no GLSL shaders: yes Texture NPOT support: yes Virtual Machine: no kf5.kcoreaddons.desktopparser: Property type "Url" is not a known QVariant type.

I'm using nvidia binary drivers, I did try various versions available over time with no effect.
