--- Comment #9 from m00nraker <m00nra...@gmx.net> --- After I studied some other bug reports, here some additional informations: Shell-Output from "kwin_x11 --replace" from a running plasma5 desktop: QXcbConnection: XCB error: 8 (BadMatch), sequence: 1157, resource id: 113246213, major code: 42 (SetInputFocus), minor code: 0 OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: GeForce Go 7950 GTX/PCIe/SSE2 OpenGL version string: 2.1.2 NVIDIA 304.131 OpenGL shading language version string: 1.20 NVIDIA via Cg compiler Driver: NVIDIA Driver version: 304.131 GPU class: NV40/G70 OpenGL version: 2.1.2 GLSL version: 1.20 X server version: 1.17.2 Linux kernel version: 4.1.15 Requires strict binding: no GLSL shaders: limited Texture NPOT support: yes Virtual Machine: no Pixel was QVector4D(0, 0, 0, 0) expected QVector4D(0, 1, 0, 1) Pixel was QVector4D(0, 0, 0, 0) expected QVector4D(0, 1, 0, 1) Pixel was QVector4D(0, 0, 0, 0) expected QVector4D(0, 1, 0, 1) Pixel was QVector4D(0, 0, 0, 0) expected QVector4D(0, 1, 0, 1) Pixel was QVector4D(0, 0, 0, 0) expected QVector4D(1, 0, 0, 1) Pixel was QVector4D(0, 0, 0, 0) expected QVector4D(0, 1, 0, 1) Pixel was QVector4D(0, 0, 0, 0) expected QVector4D(0, 0, 1, 1) Pixel was QVector4D(0, 0, 0, 0) expected QVector4D(1, 1, 1, 1) Pixel was QVector4D(0, 0, 0, 0) expected QVector4D(0.44882, 0.14882, 0.14882, 1) Pixel was QVector4D(0, 0, 0, 0) expected QVector4D(0.50064, 0.80064, 0.50064, 1) Pixel was QVector4D(0, 0, 0, 0) expected QVector4D(0.05054, 0.05054, 0.35054, 1) Pixel was QVector4D(0, 0, 0, 0) expected QVector4D(1, 1, 1, 1) Pixel was QVector4D(0, 0, 0, 0) expected QVector4D(0.3, 0, 0, 0.6) Pixel was QVector4D(0, 0, 0, 0) expected QVector4D(0, 0.4, 0, 0.6) Pixel was QVector4D(0, 0, 0, 0) expected QVector4D(0, 0, 0.5, 0.6) Pixel was QVector4D(0, 0, 0, 0) expected QVector4D(0.3, 0.4, 0.5, 0.6) Pixel was QVector4D(0, 0, 0, 0) expected QVector4D(0.134646, 0.044646, 0.044646, 0.6) Pixel was QVector4D(0, 0, 0, 0) expected QVector4D(0.200256, 0.320256, 0.200256, 0.6) Pixel was QVector4D(0, 0, 0, 0) expected QVector4D(0.02527, 0.02527, 0.17527, 0.6) Pixel was QVector4D(0, 0, 0, 0) expected QVector4D(0.360172, 0.390172, 0.420172, 0.6) kwin_core: ShaderManager self test failed kwin_core: Failed to initialize compositing, compositing disabled QXcbConnection: XCB error: 3 (BadWindow), sequence: 1298, resource id: 579, major code: 3 (GetWindowAttributes), minor code: 0 QXcbConnection: XCB error: 9 (BadDrawable), sequence: 1299, resource id: 579, major code: 14 (GetGeometry), minor code: 0 QXcbConnection: XCB error: 3 (BadWindow), sequence: 1937, resource id: 123731969, major code: 18 (ChangeProperty), minor code: 0 QXcbConnection: XCB error: 3 (BadWindow), sequence: 1941, resource id: 123731970, major code: 18 (ChangeProperty), minor code: 0 QXcbConnection: XCB error: 3 (BadWindow), sequence: 2275, resource id: 123731969, major code: 18 (ChangeProperty), minor code: 0 QXcbConnection: XCB error: 3 (BadWindow), sequence: 2283, resource id: 31457288, major code: 18 (ChangeProperty), minor code: 0 QXcbConnection: XCB error: 3 (BadWindow), sequence: 2745, resource id: 123731968, major code: 18 (ChangeProperty), minor code: 0 QXcbConnection: XCB error: 3 (BadWindow), sequence: 2749, resource id: 123731969, major code: 18 (ChangeProperty), minor code: 0 QXcbConnection: XCB error: 3 (BadWindow), sequence: 3243, resource id: 35651588, major code: 15 (QueryTree), minor code: 0 QXcbConnection: XCB error: 3 (BadWindow), sequence: 3847, resource id: 35651597, major code: 18 (ChangeProperty), minor code: 0 QXcbConnection: XCB error: 3 (BadWindow), sequence: 4568, resource id: 35651597, major code: 18 (ChangeProperty), minor code: 0 QXcbConnection: XCB error: 3 (BadWindow), sequence: 4609, resource id: 123731972, major code: 15 (QueryTree), minor code: 0 glxinfo output: https://paste.kde.org/ptbsvexvf In Plasma-Systemsettings: Switching from OpenGL GLX to OpenGL EGL doesn't seem to work with my NVidia. Scale method is set to smooth. Pressing Shift+Alt+F12 doesn't have any effect. kwin_x11 --replace doesn't change anything. kwin_core: Failed to initialize compositing, compositing disabled Can it be, that compositing support for my NVidia 7950 GTX (G70) has been dropped? Or is it a bug? Please help. -- You are receiving this mail because: You are watching all bug changes.
