Hi! I've noticed a regression using 3.7 on my Thinkpad X300.
In Cinnamon and in KDE with Desktop Effects, all graphics are slow and studdering. Moving a window results in about 5 frames per second. glxgears achieves about 14 fps, versus ~60 in unaffected kernels. X is from Debian unstable: X.Org X Server 1.12.4 Release Date: 2012-08-27 (II) intel(0): Integrated Graphics Chipset: Intel(R) 965GM (--) intel(0): Chipset: "965GM" I did a bisect on this: f047e395ddc9da6c307a10629a237502e627ed85 is the first bad commit. a7b9761d0a2ded58170ffb4d423ff3d7228103f4 is "good". If you need more information, please ask. Regards, Bernhard
