For those of you who wants to use latest version and encounters the bug that the render viewport remains blank. Here is my quick tip I just figured out:
1. Close the viewport.
2. Open the material editor (otane materials).
3. Close the material editor.
4. Reopen the viewport - it should work now.
Hope it helps a bit.
Ooh, I almost thought you were sent like a messenger to me, Smicha! I am on a tender deadline and experiencing this blank viewport. I am not on the latest version though (I'm on 0.13.82). Some of my files open fine, but my 'master' model (it's a big site so I use proxies), gives a blank VP and then every time the 'your display driver has stopped working and has recovered' message... Don't need this now!
If you or anybody else has some insights, it would be greatly appreciated. I am a little scare to install the latest version since it seems not to be a very solid release and I'm worried something else brakes at this point. But I may not have a choice. Incidentally, I get the exact same error in SU2014. It seems to be file related somehow. My precious 40 hour labour file...
