    KDE sluggish after extended usage


    I use KDE with transparency enabled and after a certain amount of usage it starts to get slow, applications take 30s-1m to start (where before they were instantaneous), and sometimes transparency effects lag. There is no processor or memory usage increase to justify this effect. This problem disappears if I restart X and appears again after using KDE after a while. Also, I didn't have this problem before enabling translucency.
    My video card is a
    Code:
     00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS/940GML Express Integrated Graphics Controller (rev 03)

    I also use 915resolution to set the appropriate values in the video BIOS so I can use the 1440x800 monitor and the laptop at 1280x800. The 640x480 is for playing Starcraft fullscreen
