Screenshot of HUD on a bad configuration

When running Euro Truck Simulator 2 with the combination of Mesa 10.3 and Linux
3.17 or newer, the game shows severe stuttering whenever a new object enters
the field of view (gets loaded to GPU RAM?) or the camera is rotated. The game
stops for a short period of time, up to several seconds, just to return to a
normal framerate afterwards. This stuttering is not present when combining
either Mesa 10.2 with Linux 3.17, or Mesa 10.3 with Linux 3.16. With Mesa 10.4
from git the stuttering is present on recent Linux versions, but much less
severe than with Mesa 10.3.
