Re: 4.4-rc, intel dri i915, regular hangs and corruptions

Hi Chris,

thanks for your answer.

I will try the latest intel driver, but in case it helps or
you get an idea, I found that it has to do with the
Antialiasing settings:

I am using an OTF font (Lucida Sans OT Regular) with cinnamon.
Sometimes when I wake the computer up from suspend to ram the 
fonts are gone.

*BUT*: Switching from (in Font Settings of Cinnamon settings)
	Antialiasing:	Grayscale
*away* fixes the problem.

WIth Antialiasing: Rgba or None the fonts remain stable as far as
I can see, while with Grayscale they are disappearing.

In fact I can turn the fonts off and on without a problem by simply 
swithcing the antialiasing.

Maybe this rings a bell at someone.

Thanks

Norbert
