From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.12) Gecko/20051215 Epiphany/1.9.4 Description of problem: Opening (or maximising) a Window, and then minimising it shows a noticeable lag in redrawing the icons on the desktop. It makes gnome feel slow (which is a shame, because everything else in FC5T2 feels faster, especially disk).

I've seen various mentions of this, but i haven't seen it myself. We need to figure out what combination of hw/sw causes it. What graphics card do you have, and what X driver do you use?
The problem goes away when I switch to a tiled background. I used a tiled background in FC4 too, and this is what I am comparing against. Since I can't tell if this is a regression or not, feel free to close the bug. On the other hand, maybe it's worth looking at the size of the new wallpaper (I can't do that at the moment)
That is interesting. What X driver do you use, and what size are the tiles you use now?
It's an ATI Technologies Inc Radeon 9100 with the ati driver. The tiles are 289x150, 4-bit PNGs.
What kernel is this occuring with? It's possible the performance change is caused by kernel debugging features being enabled.
2.6.15-1.1863_FC5smp
quite likely. there's some really nasty bugs in recent kernels which I'm trying to pin down. if performance is an issue, use an older kernel until this is worked out.
Just a "me too." I am running FC5t2 x86_64 on an Intel D945PVS motherboard with an Intel 3.0GHz HT processor and 512MB memory. My video card is an nVidia GeForce FX 5200 with 128MB memory. My monitor is a Viewsonic VA201wb 19" LCD monitor. I am running at 1600x1200 resolution, thousands of colors. When I minimize an application window, say Firefox or Evolution, it takes a few seconds for my desktop to refresh. If I set it to no background, solid black, the problem is lessened. However, it is still noticeable - it takes a good half to three quarters of a second for my desktop icons to re-appear.
the latest kernels have the heavyweight debugging turned off (There's still some features left on whilst some lingering problems get nailed down, but it shouldn't be too bad).
These bugs are being closed since a large number of updates have been released after the FC5 test1 and test2 releases. Kindly update your system by running yum update as root user or try out the third and final test version of FC5 being released in a short while and verify if the bugs are still present on the system .Reopen or file new bug reports as appropriate after confirming the presence of this issue. Thanks
