Hi!


How do i know, what is my laptop's problem? I have random artifacts, lines, freezes, but i don't know, which problem it have... How to identify that i have EDID, or VRAM error? Here is a video:

I have this with all programs and after 1-2 hours, i get lines/cubes on screen.

Things to check:
- install at least 8GB RAM
- your DSDT is patched from your own native DSDT
- do EC reset

This problem (WindowServer) was solved with Yosemite 10.10.2. Then the artifacts come back, then was solved with Yosemite 10.10.5. Now with El Capitan again.
