If you can capture this in a screenshot, that tells me where abouts in the rendering pipeline it occurs (or rather it rules out where it cannot occur). Can you also please check with -intel.git as I fixed an issue for i915c very recently? Created attachment 73675 [details]
Screenshot showing the issue
Hi, here is the screenshot.
You see two 'screens' because it was taken with the external screen attached, but this makes no difference. The rendering problem shows also with the normal laptop screen only.
If you zoom to the terminal border, you can see that it has some weird pixelization.
This happens only when the window is made inactive. When the window is active, it looks fine.
One more note: this does not happen always. Only every now and then.
You see the issue, you reboot the machine. You don't see the issue anymore. Maybe the day after you see it again.
I don't think there's any particular reason why this is related to gen3 (iirc they stopped using xrender to draw the shadows), but I'm starting the process of putting Ubuntu/unity on a pineview device. Is there anything I can do to increase the likelihood of reproducing the issue? Ah, as you have not tried since commit 98b312e579385e6e4adf6bf0abe20f8ca84592af Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Wed Jan 23 20:51:35 2013 +0000 sna/dri: Stop feeding I915_TILING_Y to mesa i915c I'll quietly presume it is a side-effect of that bug. My gen3 machine is the 'travelling' machine, my 'every non travelling day machine' is a gen4... that's why I was late with testing. Just verified and seems OK now. |
