Graphics Error in the game

[76561198386161734]

iam running Linux Ubuntu

Ubuntu 16.04 LTS

Memory: 4 GB
Processor: Pentium(R) Dual-Core CPU E5700 @ 3.00GHz × 2
Graphics: Intel® G41
OpenGL string: 2.1 Mesa 12.0.6
OS type: 64-bit

i know that's my GPU/driver may not meet the minimum requirements ( <OpenGL 3.2>)
so iam using -force-opengl to run the game, and when i started it i found the graphics very glitchy

some images from what happened (please focus in the pictures):

the game was running well in windows but when I arrived to linux I got this problem

but i have other game in steam called (Time Clickers) and i run it without -force-opengl but there's the same problem.

i realized that all games which made with unity engine meets the same problem,i have another game in steam called "time clickers" [made with unity engine] which has the same graphics error "but without using -force-opengl command" look at this picture (and focus)

Spamming threads is more likely to get you removed from the forums than it is to get you help.

As for your problem, it looks like the graphics card is going out.
