Hello,

if I have activated SKIA in my office and e.g. run a macro (no matter which one), then the surface is partly blackened out.
See picture attached.

Do you have an activated dark theme in Win 10?
What video card do you use?
Can you disable Skia in Tools-Options-LibreOffice-View dialog and look at result?

Please write here info from files:
C:\Users\Username\AppData\Roaming\LibreOffice\4\cache\opencl_devices.log
C:\Users\Username\AppData\Roaming\LibreOffice\4\cache\skia.log

btw, I can't repro it in Windows 7 with 7.1 or 7.2

No Issue if SKIA is disabled.

No.

- I have done this and everything it’s OK. 
- The issue is only present if SKIA = enabled

Can you try update your Nvidia driver to latest 461.40  WHQL version?

And I'm not sure about Intel embedded video in your CPU. Is there a video core there? If yes, try update Intel video driver too.

Thanks

Hello Roman,

I disassembled my computer and looked for hardware errors. Here I discovered that the HDMI cable on my monitor was defective.

Since I can no longer reproduce the error I reported, I conclude that the HDMI cable was the cause of my reported problem.

What I can't understand, however, is the fact that I only had the reported problem with LibreOffice. No other program on my computer showed this behavior.

Well. The problem is solved on my part and I apologize for the unnecessary work.

Thanks and best regards

Juergen
