Can you please try a window decoration which does not use animations. For example Plastik. (Personal note: since using the 195.x driver the issue is completely gone for me) also ensure you're using "nvidia-settings -q InitialPixmapPlacement" "1", "2" is (really) 10 times slower in this regard... Okay, changing InitialPixmapPlacement between 2, 1 and 0 had no effect, but using the Plastik window decoration solved the problem. I'll have to test the new NVIDIA driver, but I won't do that until Kubuntu Lucid beta is released, at which point I'll begin beta testing Lucid with the new NVIDIA driver. *** This bug has been marked as a duplicate of bug 226182 *** |
Version: (using KDE 4.4.1) OS: Linux Installed from: Ubuntu Packages ** Bug Description ** If an application is the sole window open on the screen, its animations are smooth (minimize, restore, fade-in and fade-out). However, if another window is already open in the background, then the foreground's window's animations are noticeably choppier. ** Reproducing the bug ** 1) Open two instances of Dolphin; we'll call them "Dolphin A" and "Dolphin B". 2) Resize Dolphin A to be around 50-60% horizontal and 50-60% vertical respective to the screen's width. 3) Maximize Dolphin B, and then minimize it. 4) Repeatedly minimize and restore Dolphin A (there should be no other windows showing on-screen). Note how smooth the animation is. 5) Now, restore the maximized Dolphin B. 6) Repeatedly minimize and restore Dolphin A with Dolphin B sitting behind it on-screen. On my system the minimize/restore animation of Dolphin A is noticeably more choppy. ** Enabled Compositing Effects ** For your reference, here are the effects that I have enabled: Invert, Zoom, Fade, Login, Logout, Minimize Animation, Shadow, Slide, Taskbar Thumbnails, Translucency, Dialog Parent, Dim Screen for Administrator Mode, Box Switch. ** /etc/X11/xorg.conf ** Section "Module" Load "glx" EndSection Section "Device" Identifier "Configured Video Device" Driver "nvidia" EndSection Section "Screen" Identifier "Default Screen" Device "Configured Video Device" Monitor "Configured Monitor" DefaultDepth 24 Option "NoLogo" "true" Option "RenderAccel" "true" Option "TwinView" "false" Option "AddARGBGLXVisuals" "true" Option "UseEvents" "false" Option "TripleBuffer" "1" Option "DamageEvents" "1" Option "InitialPixmapPlacement" "2" Option "BackingStore" "1" Option "PixmapCacheSize" "70000" Option "OnDemandVBlankInterrupts" "true" SubSection "Display" Depth 24 Modes "1280x960" "1152x864" "1024x768" "800x600" "640x480" EndSubSection SubSection "Display" Depth 16 Modes "1280x960" "1152x864" "1024x768" "800x600" "640x480" EndSubSection SubSection "Display" Depth 8 Modes "1280x960" "1152x864" "1024x768" "800x600" "640x480" EndSubSection EndSection Section "Extensions" Option "Composite" "Enable" EndSection ** My System ** Motherboard: MSI K9N SLI Platinum (nForce 570 SLI chipset) CPU: AMD Athlon(tm) 64 Processor 4000+ (2.6 GHz) RAM: 2GB DDR2 Video: Dell NVIDIA GeForce 7800 GTX w/ 256 MB RAM (PCI Express) OS: Kubuntu 9.10 i386 (with KDE SC 4.4.1) Linux Kernel: 2.6.31-9-rt NVIDIA driver: 185.18.36 Screen Resolution: 1280 x 960 X.org: 7.4 Qt version: 4.6.1
