Intel OpenGL graphics performance regression in F13 with mesa 7.8.1

[helloworld1]

I have installed fedora 13 on my thinkpad x200 laptop with intel GMA4500MHD graphics. Apps that uses OpenGL graphics became very choppy comparing to Fedora 12 with mesa 7.7.1 (7.7-5). The FPS is not low but the the animation will halt a short time every several frames. So the graphics experience is very bad. Any one have the same problem?

Some info:
OpenGL vendor string: Tungsten Graphics, Inc
OpenGL renderer string: Mesa DRI Mobile Intel® GM45 Express Chipset GEM 20100328 2010Q1
OpenGL version string: 2.1 Mesa 7.8.1
OpenGL shading language version string: 1.20

Tested apps: xmoto, nexuiz, warsow, openarena.

Fedora 13 is still in beta, it has some debugging code in it.... probably slows it down

I don't think it contains debug code. All debug info are stripped and put in the debuginfo rpms. A

Hi,

That's not true for the kernel in the development releases. Refer to

I have similar issue (sometimes windows not refreshing) but only with GMA4500MHD.
Another system with Nouveau seems to not have this issue.

There was a bug reported for this issue and issue was believed to be fixed in last mesa update but it is not yet fixed.

Ive been trying to track this issue and i think i have this fixed now with the following config:

2.6.33.2-56.fc13.x86_64
intel_iommu=igfx_on
Compiz/Desktop effects off

So far no more refresh issues.

I have also had a more serious issue where the whole system would lock up. This "appears" to also be fixed with this configuration. Needs more time for testing.

Once i am sure both issue mentioned above are really fixed i think i can start pointing my finger to compiz/Desktop effects.

There is a Mesa / Intel driver problem with compiz

I have seen reports that claim downgrading to mesa 7.7 fixes it.

Compiz is not started on my laptop. But the problem persists.

I am not sure if this is at all related, but I am running a Dell Mini 1012. It uses a video device identified as "N10 Family Integrated Graphics Controller." I have noticed that when running with desktop effects, various windows do not refresh properly where icons and other GUI elements do not appear on their windows. The appear when the mouse hovers over them or all at once when the window is moved.

This only seems to happen when desktop effects are enabled. It seems to work fine in standard mode even though the graphics seems to be less than solid and less than fast.

It seems with the most recent updates involving Mesa, the majority of my problems disappeared. One detail I have noticed, however, is that Pidgin's blinking tray notification doesn't blink.

You will probably need Xorg as well

Right click on the sys tray icon and make sure "Blink on new message" is ticked

I have installed the latest mesa 7.8.1-2, xserver 1.8.0-8 and non-debug kernel 2.6.33-68.
The performance issue still persist on my thinkpad x200 with GMA4500MHD. Actually there isn't any performance gain from the beta. The 3D or 2D opengl graphics stiill seems laggly even though the FPS is relatively high. Even simple 2D game like XMOTO is laggy.

I can confirm this as well, on my i915GM 2D is slower then it was in Fedora 12.
It is really noticeable in Opera, then I switch the Tabs, they switch slow, and another issue - MC in terminal window, then do resize picture in window re-draws by peaces, and not the whole window at ones. I thing it looks like problem with caching 2D, or may not enough memory for 2D textures.
I really want XAA to be available for intel Xord driver - best for 2D.

Even with mesa 7.8.1-5, it is not fixed.
