Description Antti Mäkelä 2008-09-01 13:14:21 UTC
I recently upgraded mesa to 7.0.3 (and Xorg to 7.3). Anyway, good thing is that Google Earth no longer "whites out" when zooming in. 

  What is bad that now Google earth is slow (several seconds per frame) at higher altitudes...zooming in or switching atmosphere off (In View -> Atmosphere) returns responsivity.

  Google Earth version: 4.3.7284.3916 (Build date Jun 8 2008)
  intel-driver version: 2.1.1
  Mesa version: 7.0.3
Comment 1 Vedran Rodic 2008-09-24 06:18:24 UTC
I can confirm this, on a 945GM, Mesa 7.0.3-6  (Debian version), Xorg Intel driver version 2.3.2-2+lenny4 (Debian).

Comment 2 Michael Fu 2008-09-25 02:17:29 UTC
what about the master or 7_2 branch? We've stopped development on 7.0.3...
Comment 3 Antti Mäkelä 2008-09-25 03:15:01 UTC
I did test with mesa 7.1 - same effect. Haven't tested with 7.2. Could try 7.2 rc1 though since it's in Gentoo portage tree - but does it require upgrading the entire Xorg to the pre-7.4? 
Comment 4 Antti Mäkelä 2008-09-27 11:36:10 UTC
I tested with Gentoo's Xorg 7.4 packages. Xorg-server 1.5.0, Mesa 7.2, Intel-driver 2.4.2. 

Still same issue. Mind you, the new xorg made my desktop so unstable that I downgraded right after test. I was able to repeate the problem thought.
Comment 5 Gordon Jin 2009-06-09 11:43:00 UTC
Does this still exist on mesa master branch or mesa_7_5_branch, with a recent >=2.6.29 kernel?
Comment 6 Antti Mäkelä 2009-06-10 00:03:44 UTC
I can test - Gentoo's x11 repo currently has "Mesa 7.5 RC3" available. I suppose that is appropriate?

However, before I upgrade and test - do you require kernel modesetting to be used? I haven't been able to get that to work (read somewhere that it requires a patch that's going to be included in 2.6.30) - so if it's needed, I'll do the testing after kernel 2.6.30 is out.

Yes.

Yes, we recommend using kernel modesetting. And yes, 2.6.30 is the best choice at this point, and it was just released.
Comment 8 Antti Mäkelä 2009-06-12 05:39:54 UTC
With Kernel 2.6.30 kernel modesetting works.

And yes, problem still persists. Switch on atmosphere and you get jerkiness.

Now using Xorg 1.6.1, Intel driver 2.7.1, Mesa 7.5 RC3.

Google earth has upgraded itself to 5.0.11733.9347 (build date May 5, 2009) now.
Comment 9 Antti Mäkelä 2009-06-12 05:40:29 UTC
Meaning of course xorg-server 1.6.1.

We are seeing bug#22228. It seems you are seeing different symptom?
Comment 11 Antti Mäkelä 2009-07-22 04:24:07 UTC
Yes - the fog issue vanished for me when I upgraded Mesa way back - actually the bug is something that I refer to in the opening comment ("white out").
Comment 12 Robert Huitl 2009-07-22 06:05:44 UTC
This problem has been bugging me for a long time as I didn't know about the "Disable Atmosphere" workaround. With atmosphere enabled, Googleearth is unusably slow. My configuration:

Gentoo, 32 bit kernel + userland
Kernel 2.6.30.2, KMS enabled
xorg-server-1.6.2-r1
mesa-7.5-r1
xf86-video-intel-2.7.99.902-r1
googleearth-5.0.11733.9347

Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 03)
Comment 13 Eugeni Dodonov 2011-08-23 12:45:35 UTC
I could not reproduce this issue with latest Intel graphics stack, so I'll close it - I believe it was fixed meanwhile.

If it still affects the latest versions of the graphics stack, please, feel free to reopen the issue!
