Severe OpenGL rendering issues in games

[Itai Bar-Haim]

As I also asked in http://askubuntu.com/questions/698855/severe-rendering-issues-in-games-intel-hd-4000-ubuntu-15-10

After updating Ubuntu to 15.10, 3D Steam games don't render things correctly. The issue is so severe that it is unplayable, as polygons are smeared all over the screen (see screenshots in the askubuntu link above).

GLGears works fine, so I looked for advanced OpenGL samples I can test it on but couldn't find anything, not ready to use nor something I need to compile.

My processor is Intel® Core™ i5-4430 CPU @ 3.00GHz × 4 and I use the processors graphics, i.e. Intel HD 4000 series (Intel® Haswell Desktop).
The system is 64 bit, with 8 gigs of RAM.

I tried installing the ppa:oibaf/graphics-drivers repository and drivers, but it didn't help.
I tried installing XFCE desktop and running the game from there, so there is no Compiz interference, but it didn't help.
