KDE konsole pixelation problem

I've been having this problem with konsole on Slackware 12.2. In fact, I had similar issues with the previous version. The konsole programs works fine. However, every now and then, when issuing command or if I'm compiling something, I get pixels "stuck or frozen" in the terminal. The only way to clear it is to re-size the terminal. When I'm compiling something, the screen can get pretty saturated with pixels. Not a big deal, but it's kind of annoying. So, is anyone else having this issue? I'm using the latest nvidia driver (1.85), but I've had this issue also on older nvidia cards with the legacy driver.

I'm open to ideas. Thanks in advance! :)

Didn't want to reply with no solution, but your thread has been bumped by
the boards twice now it seems, with no replies.

I had this problem when displaying Hanzi (Chinese characters) with konsole
running Slack-12.2. In fact, I was running a pretty customized urxvt to get
proper display of those fonts.

Since upgrading to Slackware64 -current, that problem no longer exists. The
reason I hesitated to reply is that I cannot tell you what change has stopped
the "ghosting" of characters on my screen. For me issuing "clear" or "reset"
did not make them all go away, but if I clicked on the tab of another session
in that konsole then went back, they were gone.

Bruce,

Thank you so much for replying. I was about to give up on this. The issues you describe are the same I'm having. I was thinking it was the nv driver, but I confirmed having the same issue on a different box with a different video card (matrox card). I've even tried adding "Composite" Disable on my xorg.conf file to no avail. It's no biggie. I was just curious if I was the only one having this issue.

If there are things (configs, apps) which we can compare/check, let me know.

Those issues occurred on this Asus M2N-E with:

Code:

02:00.0 VGA compatible controller: nVidia Corporation G70 [GeForce 7300 GT] (rev a1)

and also on my Lenovo T61 laptop with:

Code:

01:00.0 VGA compatible controller: nVidia Corporation Quadro NVS 140M (rev a1)

and both boxen running NVIDIA 185.18.14 and using "nvidia" as the driver.

Hmm...I'm going to try and see if I can replicate the same issue on my other box (the one with the matrox card). I just remember that I used have an old nvidia card in it. I'll give it a spin when I get home from work and I'll report later tonight. It could be an "nvidia" issue. Also, I'll make sure and see if I can replicate the same thing with the opensource driver of nvidia ("nv").

Bruce,

I just tried using the konsole on the other box (the one with the matrox card) and I can confirm that is doing the exact same thing. So, we can discard the nvidia driver being the problem. I'm stomped. Not sure where else to look at other than the xorg.conf file.

It's so short I'll post the entire thing:

The font section is definitely different from mine with Slack-12.2.

I have a box here I'm giving to someone, which requires a fresh install.
It was going to get -current, but since you're running 12.2, it can hold
that while we work through these issues. But first, a kip ...

Here's mine, although I don't think it's related to xorg.conf. Maybe it's related to a konsole setting.

Bruce,

I've pretty much given up on this issue. The only workaround I found was to use Terminal from XFCE. So far, it works great! In fact, I like it much better than konsole. Thanks for all your help!
