    window trembles when dragging

    hi there,

    when I catch a window with the mouse at the upper border and drag it it "trembles" a lot, under KDE I can also drag a window by holding down ALT and clicking right into the window somewhere, if dragging the window like that it trembles much less, can someone explain this behaviour ? It makes no difference if I use fvwm2 or KDE, besides that only KDE allows to drag the window by pressing ALT and moving the mouse.

    The dragging of windows under X11 seem to be much smoother with a gfx card using a GWorse chip from Nveragain

    my system:
    XFree86 4.2.0
    1024x768@75 Hz 16bit color depth
    MGA G400 16 MB
    DRI enabled
    Duron 750

    here's my XF86Config (I omitted Section "Files" to shorten the whole thing a bit)

    Section "ServerFlags"
    Option "AllowMouseOpenFail"

      sorry....couldn't post the log earlier...

      driver: "beta 2", the latest from Matrox for G400 and Xfree 4.2.0
      OS: SuSE Linux 7.3, kernel 2.4.18

      oh, just see this forum doesn't accept messages > 10000 characters so i split the XFree86.0.log in several parts

        I used "split" to split the log into 3 9000bytes chunks but even that was not possible with that forum...
        Now I zipped it and try to attach it, hope it works now...

          That is quite strange, because they are very standard XF86Config and log.

          Try removing some unnecessary modules and Option "Accel", see if it makes any difference.

          Does it only apply to windows moving? Whats the average CPU usage during movement?

            Yes, it's only when moving windows, besides that no performance problems and no other image quality problems, aver. cpu usage according to xosview something between 30-70 % sometimes even up to 100% for a few milliseconds...

            The XFree RPM's are from SuSE, maybe they have done something when compiling X that causes this, that's the only thing I can imagine, the card itself is okay

            I don't mind too much about it, just thought there might be an easy fix, maybe I try X directly from xfree86.org or another distro.....

            thanx anyway
