SOLVED Cura 4.5.0 Rendering not working

[Penguin_fach 1]

This one is driving me crazy!

 

I recently upgraded to Cura 4.5 but no matter what I have tried the rendering of opened STL files remains stubbornly black and is effectively unusable because the slicing intent cannot be viewed. If I roll back to Cura 4.4.1 rendering works just fine.

 

I am running Windows 10 Pro with DirectX up to date. The system has GPU on the motherboard plus external graphics card to support multiple monitors. These are Intel HD Graphics 400 and Nvidia GeForce GTX 660 respectively. All the hardware is running fine and drivers are up to date with no conflicts.

 

I have tried removing and reinstalling Cura multiple times including manually purging everything I can find. I have redownloaded the original installer but this makes no difference.

 

I know that my hardware is not top drawer but it is no slouch so it isn't a case of trying to run on underspec'd hardware.

 

Does anyone have any ideas I could try or insights that might help? I would really like to crack this quickly because I am trying to set up PETG printing of face shield head bands and a couple of the features in 4.5 would be useful.

Can you zoom out?  Are you in "PREVIEW" mode?  Is color scheme set to "line type"?

 

If so, then I'm guessing it's something to do with openGL

How embarrassing! How many years have I been using this and I have never actually looked at the color scheme settings?

 

I can only apologise for inexcusable brainlessness.
