This is most likely an issue with your graphic card. Check to make sure it is a SolidWorks approved card and that you have the latest driver installed.
Check your card here - Graphics Card Drivers | Hardware & System Requirements | SOLIDWORKS
Run Solidworks RX diagnostics and get back to us. It is listed under Solidworks in your programs under the start bar (using a PC)
Hope this helps,
I did some more research and did find out that this is indeed a graphics card issue, mine is an Nvidia GTX 960, which seems to be not supported by Solidworks. I also did try getting the latest driver for my graphics card, but it was already up to date. I found out when I run Solidworks using OpenGL the error did stop, but of course that is not a permanent fix. However, I also tried to reproduce this error again without OpenGL when I replied to this post today I could not get it to happen, so this leaves me even more confused than when I started. Is there any way to help prevent it from happening in the future?
Only thing I can think of if get an approved card and you shouldn't have any problems.
So, here is what you did 1) had the problem, 2) enabled OpenGL - no problem, 3) disabled OpenGL - also no problem.
I'm guessing that somewhere between 2 and 3 you closed out of SWX completely and/or rebooted. Since you did not actually update your video driver it is a puzzle what could be going on. Although, I have seen where some software, including graphics software, can get confused and just needs to be rebooted.
I have been seeing a lot of posts related to graphic card issues with the GTX 960 card.
What they told us at SWW in the Administrators boot camp, was
when you have a graphics problem be sure you do NOT have the latest driver for the card.
SWX does not get the drivers with enough time to even test them - let alone certify them.
Often the drivers are released with little or no notice to SWX.
The recommended action is to find the latest CERTIFIED driver and use that and disable the automatic updating of your graphics drivers. If your board is not certified at all (the GTX cards are not certified) then you should still try older drivers and see if the problem clears.
I had this same issue with Windows 10 and it is related to the windows scaling behavior. Right-click on your desktop background and select "Display settings" then go to the "Change the size of text, apps, and other items" to 100%.
Or you can disable the scaling for SolidWorks alone. You right click on the SLDWORKS.exe in the install directory then go to the Compatibility tab. Next you select the "Override high DPI scaling behavior". Finally in the dropdown select "Application". This will prevent Windows from trying to scale SolidWorks causing the tiling affect you're seeing.
