Bespin+Qt4.5 is know to produce bugs (and even crashes..)

Anyways: what graphics card/drivers are you using ?
Thanks

Comment 10 Konstantin 2009-03-15 11:53:35 UTC
comment - I see same bug in opera-shared-dev (when scrolling web)
Comment 11 Robert Knight 2009-03-16 01:57:00 UTC
Couple of things to try:

1.  Try starting Konsole with -graphicssystem raster
2.  Turn on the menu bar on in Konsole
Comment 12 Konstantin 2009-03-16 11:14:42 UTC
Starting Konsole with -graphicssystem raster : look ugly, but work correctly. No depends on menubar. (Tried with and without). --graphicssystem native causes bug
Comment 13 Konstantin 2009-04-04 13:36:52 UTC
Retest in 4.2.2. With graphicssystem native and Compiz (or KWIN compositing) bug exists
Comment 14 Konstantin 2009-04-04 13:59:30 UTC
With KDE 4.2.68 also appeared:(
Comment 15 Konstantin 2009-04-04 18:24:18 UTC
Other test: appeared only with legacy nvidia videocards. This cards are dropped for effects?
Comment 16 Konstantin 2009-04-04 18:25:36 UTC
I see this bug on Nvidia 6600 and my Nvidia GeForce 2 MX
Comment 17 Robert Knight 2009-04-05 14:03:10 UTC
Hi Konstantin,

I'm afraid to say that a fix for this is really down to NVidia.  The best I can suggest is for you to use -graphicssystem raster in the meantime.

I could turn off the scrolling optimization which causes problems with the graphics card and drivers that you are using but the trouble then would be really choppy scrolling for everyone else using Konsole.
Comment 18 Robert Penz 2009-08-06 17:32:39 UTC
Same happens on Kubuntu Karmic with KDE 4.3 final and following card:

01:00.0 VGA compatible controller: nVidia Corporation NV28GL [Quadro4 980 XGL] (rev a1) and I've installed the newest Nvidia driver available (NVIDIA-Linux-x86-96.43.13-pkg1.run)

It works after setting -graphicssystem raster and i don't see a difference. So for me the work around works.
Comment 19 Konstantin 2009-08-08 16:34:17 UTC
On newest NVIDIA drivers (185.xx from Mandriva repos) the bug do not appear. It appear only on legacy drivers (96.xx) My testing...
