KDE-strange rendering/behavior

RJQ · 2010-08-31 19:50:08

Description: at some point the graphics and font change color/background and they look like garbled, whole desktop slows down (slow response to any action) re-login or reboot is needed to normalize.

I have this kind of a graphical problem with kde, my video card is one of the old badly supported ones (intel 845) yet this problem just occur while in k-desktop environment, (I have another partitions with gnome/lxde) it happens since 4.4 and randomly, in this days I am thinking that my desktop themes may be wrong and more than one theme is trying to show at the same time, but also once this behaving occurs the whole screen slows down at the point that I have to re-log in to go back to normal.

any information/comment is much appreciated. thanks.

It's not a bug it's a feature
When your desktop requires additional resources (like when you're runing some heavy task) it automatically suspends desktop effects. You can always un-suspend them by pressing Alt+Shift+F12.

Thanks guys for the responses, the problem here is that desktop effects are disabled by default, since 4.4 all desktop effects in my kde desktop are grayed out (not that I use them before any way)
The shading-garbled appears just on mouse hovered items but then stays that way, some part like the window border buttons "blink" on hover. any other clue? : )

Are you using KMS/Plymouth?

RJQ · 2010-08-31 22:22:58

No Plymouth, KMS is enabled by default, I had tried with kms disabled but then there is no way to use the desktop, (will crash or freeze)... I use in this same machine gnome and lxde, all of them updated, I am thinking that the combination of kde/xorg-intel/my video card it may be a no go... yet when it work (sometimes for hours) it does it flawlessly. ?

Wierd. That was, kind of, my best shot (I know that Plymouth can cause similar behaviour).

Maybe it's related to the 2.6.35 I/O congestion https://bbs.archlinux.org/viewtopic.php?id=103346

no worries for that, it is just as weird for me too. I still auspicious of the theme though.

One more try, but don't expect much.

Run „oxygen-settings" and in second tab disable animations, than see what happens.

Good to know that, thank you for the info, didn't realize that something of that sort was also happening, yet I thing I may got a buggy KDE system, in my Gnome partition I have also high cpu loads but no graphical problems at all.

Trying right now, completely forgot there is a separate "switch" for animation in the oxygen theme and also the window decoration, let us see what happens, but since the kernel upgrade yesterday I haven't had the problem yet, nevertheless the disabling of the animations are making a least my desktop snappier, will comment if that helped this strange behavior. I am thinking on deleting the "oxygen/air for netbooks" themes too, parts of them pops up in the air theme. I been barely half an hour on kde since the updates, will see...

Thank you for the information!

Oh well, just my luck, the problem persist, I will keep blaming intel-xorg driver + kde, only difference is that now is just in the plasma workspace and the font color on the window decorations what renders wrong, leaving the rest of the windows normal but slow. will see with next updates of the driver.
