--- Comment #4 from DonMartio <donmar...@larkos.de> --- Thanks, you where right regarding the output in the .xsession-errors. I recompiled the driver without a useflag which changed some libGL prio and now get the expected output: OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: GeForce GTX 970/PCIe/SSE2 OpenGL version string: OpenGL ES 3.2 NVIDIA 367.44 OpenGL shading language version string: OpenGL ES GLSL ES 3.20 Driver: NVIDIA Driver version: 367.44 GPU class: Unknown OpenGL version: 3.2 GLSL version: 3.20 X server version: 1.18.4 Linux kernel version: 4.7.2 Requires strict binding: no GLSL shaders: yes Texture NPOT support: yes Virtual Machine: no But the problem remains. All Windows invisible (with a slight shadow). I'll investigate further. Thanks so far. -- You are receiving this mail because: You are watching all bug changes.
