Can see problems with screen elements

On Linux Mint 17 64bit have a problem with rendering screen elements after some time. Mostly when laptop have a few tasks, not with graphics. i965, mesa 10.3.0
See attachments.

We need your dmesg and Xorg.0.log from after the errors start appearing.

My prediction is that this is the L-shaped swizzling bug on gen4 that will finally be fixed in v3.19:

Indeed that should be fixed in 3.19. Thanks for the report.
