In some, but not all, photospheres (360° pictures, a Google+ social network feature) there are severe graphical glitches.
They always happen in the same photospheres at the exact same position. Happens in both Chrome 33 and Opera.
A friend of mine with a completely different system (he uses Intel HD graphics too (same driver)), has the same problem, with the same photospheres.
Other photospheres work _always_ fine.
Example link: Nico Möbius - Google+ - 1. Photosphere mit dem selbst gebastelten Nodalpunktadapter… (need to be logged into Google account and Google+ to view). Turn around a few times and you should spot the glitches, they are very obvious.
My system:
Gigabyte Brix Pro, F4 BIOS, Win7sp1 Pro x64, Intel i7-4770R HD 5200, driver 10.18.10.3496
System of the before mentioned friend features an older Intel i7 (no Haswell, same OS, same driver).
Since this happens on completely different machines and in 2 different browser it seems very likely this is a driver issue.
