It's easy to create corrupted borders

kev009 commented 8 years ago

If I ran glxgears and moved a kde decorated window around I saw very similar borders on SB

It's always possible that one can do this on Linux too. I need to start doing apples to apples testing.

I am having similar issues on my Haswell laptop. Running mate - pretty much all text and many icons are missing or completely corrupted. I enabled dev.drm.drm_debug=-1 which as expected generated heaps of logs but nothing obvious to my eyes.

FWIW - on the same hardware using the kernel and i915kms modules which are shipping with 11-ALPHA5 I am able to run mate w/o any corruption. LMK if logs or anything of that nature will help debug this.

Focusing on getting igt to work.

I have a similar issues on my Haswell desktop. I am using drm-next-4.7 branch kernel. If you know where the problem is occurred, tell me please. I am waiting for your answer. Thank you.

I don't know where the issue is. I believe there is some sort of memory update serialization issue - one update is starting before another has finished.

I'm busy fixing more serious issues impacting amdgpu at the moment but I'm sure this is a problem there as well.
