Version: (using KDE 4.3.1) OS: Linux Installed from: Debian testing/unstable Packages Hello, Before when I used to switch between virtual desktops, X-Chat would load instantaneously, I would not see the white/flashing/refresh of the text in the window. http://home.comcast.net/~jpiszcz/20091024/P1040018.MOV All other applications, xterms, etc, suffer as well but not as much as X-Chat. Justin.
Do you use the desktop effects? (hard to say from the video) -> In case: Does the speed improve if you set "Keep Window thumbnails" to "always"? (This will prevent windows from being really un/minimized) In general this appears to be a problem on mapping (i.e. unminimizing) and could either be a bug or misconfiguration in the video driver or something using you cpu, so: - please provide additional info on your hardware - monitor the cpu usage (some plasmoid, ksysguard, conky, top in doubt) and see if and what takes much/most cpu resources
Hello, Not using any desktop effects (i am also running xinerama, and they are not supported when running xinerama) I ran top & ksysguard, its Xorg not plasma. Xorg @ ~20-21% CPU Plasma @ 1-2% CPU Also tried fvwm2 (it is a little faster) but the same problem remains with the white/flashing/etc.. Hardware is: NVS Quadro 440 03:00.0 VGA compatible controller: nVidia Corporation NV43 [Quadro NVS 440] (rev a2) 04:00.0 VGA compatible controller: nVidia Corporation NV43 [Quadro NVS 440] (rev a2) CPU: Q6600 Driver: I tried several drivers (thinking one may make a difference) NVIDIA-Linux-x86-185.18.36-pkg1.run NVIDIA-Linux-x86-190.32-pkg1.run NVIDIA-Linux-x86-190.42-pkg1.run None made a difference, in each rendition / driver test, the result was the same. This case can probably be closed as the issue happens in another window manager, for the record the packages upgraded (most of which yesterday) are shown below for reference: acroread-debian-files

FYI, the window manager process would be "kwin" Marking UPSTREAM as this is atm a driver issue and KDE apps are likely affected (indirectly) as well. If you do not need the GL acceleration or nvidias twinview support you should try the nv or nouveau driver However as this is apparently about mapping and thus memory allocation you should a) check your xorg.conf - in doubt, try with a plain vanilla one (i.e. just move your /etc/X11/xorg.conf out of sight - don't delete it ;-) this should bypass forced AGP (iff), AllowSHMPixmaps (usually rather a bad idea) or PixmapCacheSize settings, invalid dri loading (nvidia drivers ship their own) and deactivated RenderAccel if anything special regarding the driver, you should consider including Section "Extensions" Option "Composite" "Disable" EndSection to force Composite OFF b) the nvidia driver provides different memory allocation strategies: nvidia-settings -q InitialPixmapPlacement nvidia-settings -a InitialPixmapPlacement=[0-n] will allow you to alter them with more or less instant results (though iirc this should only affect offscreen pixmaps)
