Macbook air mid-2011 visual glitch problem

I face some problems with my macbook air mid 2011 (HD 3000), some weird visual glitch on the screen (see pictures).

Is there any solution or fix? Does anyone else have the same issue?

I own a Apple care(june 2014).

I have already contacted Apple, they done a Hardware test and the test revealed nothing so they do not believe me completely... And they don't know what to do (seriously) ...

Thank you in advance.

Best regards.

Based on our discussion and some fact finding above:

I would say your hardware is fine /the Intel HD3000, but it could be on its way out!, means it could be dying the slow death.

You can double check and run a stress test for the GPU using this little program, or look for your OSX version.

GpuTest 0.6.1 is a bugfix release for Mac OS X only. The CSV file (for benchmark scores) was no longer generated at the end of a benchmark. This CSV file is stored in the root folder of the current user (_geeks3d_gputest_scores.csv).

However, I still think you have a software (programs) interference issue. Remember the Intel GPU uses shared memory, so that could lead to a problem you are having.

Finding out which program is interfering could be tricky, but you had to just turn them completely off one at the time.

In your case I recommend:

Use an external monitor (or LCD Television) to:

1-see if it is a problem with the build in display

2a problem with the flat band cable to the build in display

3-actual problem with the GPU chip
