gtkperf with drv-intel 2.20.18-1.fc17
The biggest slowdown from gtkperf was the GtkDrawingArea - Text time: with the old Intel driver it was 0.35 seconds, and with the new Intel driver, it is 7.34 seconds.

How's 2.20.19? Do you happen to have a DisplayLink USB gadget plugged in? Created attachment 691153 [details]
gtkperf with drv-intel 2.20.19-1.fc17
I rebuilt the 2.20.19-1.fc18 package in mock for F17. Unfortunately there was no change in gtkperf performance, and windows are still visibly delayed.
I don't have a DisplayLink USB device - it's just a standard Dell laptop, and I'm using the laptop screen.

Xorg log with drv-intel 2.20.19-1.fc17
I suffer from the same issue with a similar laptop (Dell Latitude 2120) and a similar video card (Intel Corporation N10 Family Integrated Graphics Controller (rev 02)) with driver i915. I observe a very high cpu usage from the Xorg process which disappears if I downgrade to the previous version. Feel free to ask me more details.... Let me mention that i do not provide any specific i915 option to the kernel and the issue arises whether I am using kernel 3.6 or 3.7. This bug should be fixed by upgrading libdrm to version 2.4.41 or later. libdrm-2.4.42-1.fc17 has been submitted as an update for Fedora 17. https://admin.fedoraproject.org/updates/FEDORA-2013-2298/libdrm-2.4.42-1.fc17 Created attachment 701259 [details]

I've updated to the following versions:
xorg-x11-drv-intel-2.21.2-1.fc17
libdrm-2.4.42-1.fc17
and performance is as I expect. Thank you!
libdrm-2.4.42-1.fc17 has been pushed to the Fedora 17 stable repository. If problems still persist, please make note of it in this bug report. |
Created attachment 686117 [details] output of lspci -vvv Description of problem: X is perceptively slower with the xorg-x11-drv-intel-2.20.18-1.fc17 package in updates-testing. Scrolling is jerkier, Javascript animations stutter, and when I maximize or minimize windows in xfwm, I can see the windows "painting" before the actual contents appear. When I downgraded to xorg-x11-drv-intel-2.20.16-1.fc17 the problem went away. I then upgraded back to xorg-x11-drv-intel-2.20.18-1.fc17 and the problem appeared again. Version-Release number of selected component (if applicable): xorg-x11-drv-intel-2.20.18-1.fc17 How reproducible: Always Steps to Reproduce: 1. yum --enablerepo=updates-testing update xorg-x11-drv-intel 2. Restart X Actual results: Performance is slower and jerky Expected results: X works as normal Additional info: My laptop is a Dell Inspiron E1405, Intel 945GM Chipset.
