Xorg logfile with intel driver 2.20.19
Hello,
Regular 2D rendering has been much slower since 2.20.18 on an old
Macbook with the following specs:
Kernel: 3.6.11-1-ARCH x86_64 (64 bit)
Desktop: Openbox 3.5.0
Distro: Arch Linux
Card: Intel Mobile 945GM/GMS 943/940GML Express
Integrated Graphics Controller
X.Org: 1.13.1
driver: intel
Resolution: <a href="mailto:1280x800@59.9hz">1280x800@59.9hz</a>
GLX Renderer: Mesa DRI Intel 945GM
GLX Version: 1.4 Mesa 9.0.1
In particular, window redrawing is very choppy, and moving / resizing
windows is much less responsive than before.
For control, no other software was updated on the system, and a
reversion to 2.20.17 immediately fixes the problem. There are no notable
differences between the Xorg logfiles when using 2.20.17 vs 2.20.19
(attached).
I have decided to report here since the Arch package applies no patches
and configures with just --prefix=/usr --enable-dri
Thank you for the excellent software.</pre>
