with or without firefox everything fine here ( arhclinux KDE 4.1.2 nvidia 8800 driver 177.80 )

This only happens for a moment before the actual menu content shows up. Long enough for people to see it and say: "Oh, this Linux thing is ugly! I'm gonna stick with my XP!

Yes I notice this graphics error too, but it happened to me only when I open the Kick-Off/Classic Menu for the first time. After that the Glitch is no more present for the rest of the KDE-Session. I noticed the Glitch in every KDE4-Version (4.0.x - 4.1.x) I`ve used by now.

It also happens when opening new windows, before the content shows up I get this kind of garbage. It was present in KDE3 too, but was not that noticeable. Also, it happens with or without KWin compositing or with Compiz. All the same.
Important clue: This only happens when Firefox is or has been open

That is really bad for you. Except for the Kick-Off/Classic Menu everything else is fine for me. I use Kubuntu Intrepid RC with Nvidia Geforce 7300GT (177.80)

I think this is a kind of bad Speed Issue. So I hope it disappears after Qt4.5 is released.

I have the same issue in GTK apps: Thunderbird, Firefox, Open Office (very bad) when using KDE4 in Arch. The graphics chip is an Intel 945GM.

The same machine does _not_ have this problem with KDE4 from the Lenny backports on MEPIS. However, in order to get the slow firefox scrolling issue tackled, I had to add a line to xorg.conf: Option "EXANoComposite" "true"

Maybe that did the trick?

Running openSuSE 11.0 with Intel 965GM graphics, and I am not affected... i use the oxygen theme in both Plasma, Color Scheme & KWin ( Window Decoration )
have run firefox and with(out) KWin 3D effects.

relevant section of xorg.conf it is of any help to those who suffer from this:

Code: Select all

 
  Option       "ExaNoComposite" "false"
  Option       "AccelMethod" "exa"
  Option       "MigrationHeuristic" "greedy"


It looks like I solved the problem. I copied kwinrc over from my MEPIS install (no glitches) to my Arch install (glitches), and the problems went away.

Now, what the exact differences were, I need to analyze that....

This is a very important point. The menus show trash because they don't load on time. Why aren't they loading fast enough? I think this should be done so the menu does not show up until it is loaded. I think I'm gonna report this as a bug.

I've tried this configuration with no success. It is pretty much the same as it was before.

I think we would be very much interested in seeing this.

Here's the kwinrc file that seems to have resolved the problem for 90%.

I do experience it on some dialog boxes, but it hs much improved.

I see this only on the first time using kickoff, then it works fine afterward. Sometimes I see it in a popup or similar, but like kickoff, ofter that it is all good.

I do get a brief, full-screen 'flash' (or screenshot) of my desktop as it was at logout when KDE4 restarts, sometimes corrupted but usually its 'normal'

kwin ON, older laptop with ati 7500 mobility

Sorry, looks like I was too hasty in my celebration. At first the problem seemed to have disappeared, but during the day it got worse as I was using my system more. Looks like Kwin has some rendering issue in specific configurations.

It only happens with Desktop Effects enabled. With these disabled everything draws fine, so I suspect an Open GL acceleration or compositing problem....

No desktop effects, no compositing, no firefox started... but the problem occures.

Are you sure Firefox wasn't started before? Did you test it after a clean reboot?

I am using kubuntu 8.10 and I have to sadly admit that the same problem exists on my machine. I was told that this is sort of a distro-related problem, the person told me that kubuntu just isn't a very implementation of kde anyhow. Is it so? I am really thinking about trying one Mandriva or opensuse.

I am seriously considering migrating to OpenSUSE as well. I'm fed up with (K)Ubuntu and their very own way of doing things... badly... For instance, in Ibex, the bluetooth stack is broken, but they released anyway... Screw them.

So, I'm waiting for OpenSUSE 11.1 that should be released in mid-December.

Agreed. There always seems to be way too many distro-specific bugs in Kubuntu. And I don't think it was very smart to keep KDE4 AND KDE3 settings in .kde. That's bound to cause problems sooner or later.

As far as OpenSUSE goes, I'm running the beta of 11.1 on my main machine right now. There are a couple of glitches here and there, but is generally rock-solid. That said, I will still do a clean install when it goes final since I've experimented quite a bit with this installation.

If you want to stick with an easy Debian like distro: I installed the latest MEPIS beta and then installed KDE4 from the Debian backports. It works splendidly!
