In each environment, click the option button
Adjust it in View -> Application Display.
After adjustment, you must turn off the edge and run it again.
I also suppose the graphics card or the driver to be the reason for that behaviour.
But - I know You cann't change this - for over 15 years now I have given me a commitment:
"Never ever I will use an ATI card in any of our computers!"
I had immens troubles with several applications, not only SE but also others which are using OpenGL
May be this has changed in the meantime, but believe, I will not be the next tester to find out it!
Coming back to Your problem, change the option for graphic card usage to not fully use hardware or even less.
I think this will solve the issue.
You also can try to turn off the glowing (see picture)
This was an issue very often in the last cople of years with different cards here
Hope this helps
It may be not too late for some users with this issue, this is a problem related to an outdated or malfunction OPEN GL, for some reason old ATI video cards haven´t had too much attention from AMD lately.
I had the exact same issue on a DELL PRECISION M4600 (VC: ATI FIREPRO M5950) running SolidEdge ST9 and I have just solved it a couple of hours ago.
The solution apparently relies on updating the AMD CATALYST CENTER to the lastest BETA DRIVER, I used this one, it runs smooth now: http://support.amd.com/en-us/kb-articles/Pages/latest-catalyst-windows-beta.aspx.
Funny thing, though, now in the device manager it displays an ATI HD6700M Series as the video card driver (actually it is an ATI FIREPRO M5950)
