This should be fixed in 5d46994206335361a2b2. Unfortunately, I'm unable to 
recreate the issue on my system - please, verify the fix worked.

Thanks

5d46994206335361a2b2 reduces the problem, but visual artefacts are still 
visible.  The fickering still occurs, but probably only on about 10% of all 
frames, even when the sphere is not being manipulated.  It's hard to capture a 
screenshot, but here is one.

Yes, this seems to work.

Note that there is now a one pixel white line drawn at +/- 180 degrees 
longitude which appears at some orientations.
