**System Information**
HP Pavilion 14-bf153sa running Windows 10, Nvidia GeForce 940MX
**Blender Version**
Broken: 2.79 5bd8ac9
Couldn't find a version that worked
**Short description of error**
When blender is run using Nvidia graphics card (right click -> Run with graphics processor -> High-performance NVIDIA processor), the window that opens is entirely white, no UI visible, and no way of interacting with it. The console outputs:
```
AL lib: (EE) UpdateDeviceParams: Failed to set 44100hz, got 48000hz instead
found bundled python: C:\Program Files\Blender Foundation\Blender\2.79\python
```
I put opengl32.dll in the same folder as the executable as suggested here [[ https://developer.blender.org/T37027| https://developer.blender.org/T37027]] - blender runs fine, but incredibly slowly.
When blender is run using integrated graphics (right click -> Run with graphics processor -> Integrated graphics) it runs fine, but works very slowly in some regards including selecting objects.
I assumed it was a problem with graphics drivers, but I had the latest version installed from the nvidia website.
Thanks in advance for any help
