Description of problem: Serious xorg memory leak when using KDE's Background changing functionality (Desktop background changing to random pictures). Version-Release number of selected component (if applicable): 3.5.x How reproducible: All the time Steps to Reproduce: 1. Right click on KDE desktop, choose Configure Desktop, slideshow, choose a bunch of pictures, set random and a time of 5 minutes. 2. Monitor top during each background change. With my 2 monitor desktop (does use NVidia card and driver), and it uses up ~ 5 and 17 MB per change and is never freed. Over a typical weekend, I had used up over 4 GB for Xorg server. Actual results: Swaps out. Xorg uses over 8GB virtual mem (~ 2 - 4 GB real). Node becomes slow. Expected results: It shouldn't take up the extra memory at each change and never release it. Additional info: Backing Store and Save-unders enabled. I am using an NVidia card with an NVidia driver. I have seen this primarly on x86_64 (64 bit). I am seeing this with and without KDE translucency enabled.
i cannot reproduce this issue with KDE.3.5.5 in FC6-update. Which kde version did you install on your machine? please attach the output of "rpm -qa | grep kde". Does the problem appear if you use the opensource nv driver? Does the problem appear with gnome-desktop?
I can see something similar to this with the ati fglrx driver. If I am building an rpm from source and it is writing a whole bunch of stuff to the console very rapidly than the CPU used by X is going up to 80%. As soon as the writing on the konsole slows down CPU goes down too. Some kind of rendering issue but I am not sure where the problem lies! KDE, Xorg, ?
could please attach the output of "rpm -qa | grep kde". Does the problem appear with gnome-desktop? it seems a bug in Xorg
This is appearing to be a problem, so far, with KDE random background and 3rd party graphics drivers. I have a laptop running FC6 using the random background setting for KDE using latest updates for KDE, and after 5 days of being up, plus running the KDE translucency setting for 4 of the 5 days, I only have used ~ 110 MB real (377 MB virtual), which is what I would expect for all of the usage that my laptop gets (several tabs open in Firefox, plus open images, plus several terminals open, and VNC viewer running). I tend to think that it is a combination of the third party driver (in my case Nvidia, and in the other persons comment, the fglrx, which I have had nothing but problems with on this laptop. In fact, I have better luck running the ati open driver than the fglrx driver for my mobile radeon. Just goes to show about open source programming...). Anyway, do you have any channels that I should submit this up to through NVidia to see if they have any info. This has been happening for a while (Even through FC5, and maybe even FC4).
