The annoying part of the problem that none of our student computers has the issue, they work fine.
The only differences are that the machine is connected to two projectors (via a splitter) and the that they run software that remotely displays the desktop called ABtutor.
I have tried
Unplugging the projector
Changing the sampling settings in SketchUp
Checking the colour depth, it’s 32 bit
Changing the resolution from 720p to 1080p (projector is 720p)
Disabling the ABtutor program, parts of the program are still there but the mirage display driver is gone
Setting the Quadro as the primary graphics card
These are likely the problem. Especially the second part regarding the remote desktop display. Disconnect the projectors and use the local display only. Reboot the computer from cold–not just Restart. Don’t use the remote desktop option. Does SketchUp display correctly?
I swapped the machine out with a student computer last night and Sketchup worked fine with just the projectors.
I then put the original machine back and uninstalled Abtuor, restarted the machine and Sketchup is all good.
I reinstalled ABtutor but did not enable any optimisations
(but the screen refresh on the student computers is quite slow)
They have been using ABtuor to teach Sketchup since version 8, so I guess we have been lucky. If I get a chance I will submit a case to the vendor to see if they can fix the issue.
