I am having a strange issue with solidworks 2017 thumbnail and print previews.
In the assembly file I zoom into an area of the screen and select print preview and the image is all messed up and if you print it prints this messed up image.
The open recent document thumbnails also show as a messed up image.
Capture 1 shows the screen zoomed in
Capture 2 shows the print preview
Capture 3 shows the assembly file
Capture 4 shows the 'open recent document thumbnail.
I am running Solidworks 2017 SP2 on windows 10
I also have another system here with a similar problem
