Description solsTiCe 2008-09-14 11:39:50 UTC

Version:            (using KDE 4.1.1)
OS:                Linux
Installed from:    Unlisted Binary Package

when i edit a new mail, and have to move the cursor around to make typo correction, the cursor is slow to move

for example, if i hold the left arrow key a while to go back, and release it, the cursor continue to move a while before stopping to move as if there is a delay or as if the cursor is slow to react.

Confirming. Even worse here.

When editing a reply in KMail from KDE 4.1 (Ubuntu Intrepid) text typing, especially inserting between existing blocks of text, often becomes so slow that KMail is hardly usable. There can be a lag of several seconds between the time when text is typed and appears on screen. Scrolling goes the same poor way.

This bug didn't exist at all on the same system with KMail from KDE 3.x, and on KDE 4.1, joined to the other bug that KDE 4.1 doesn't manage the SSL certificate which I need to connect to my SMTP server, it will soon make me sadly quit using KMail (which I've enjoyed since it existed) in favour of another non-KDE MUA :-(

I can confirm too. NVidia-drivers make the problem event works.. Also moving the cursor in kwrite is really slow. Seems like a general problem.

This seems to be a duplicate of Bug 119281

Comment 5 Thomas Zell 2009-04-05 20:22:44 UTC

I have now upgraded both KDE to version 4.2.2 and the NVidia driver to 180.44. Now it works perfectly!

Comment 6 Søren Holm 2009-04-05 21:02:57 UTC

Confirming too.

Comment 7 solsTiCe 2009-04-06 16:52:08 UTC

yes it seems to work correctly now with kde 4.2.2 now. (with nvidia 180.29 here)
no slowness anymore

Comment 8 Allen Winter 2009-04-07 02:17:59 UTC

ok, then we have a solution.
marking this one as fixed.

well I still have this problem in KDE 4.2.3 (kubuntu jaunty + ppa)

run "top" in a konsole and
just open the kmail editor and start typing in the middle of a long line:
"top" reports that xorg uses 80% of CPU !
(yes I mean xorg, not kmail itself)
of course it soon becomes very slow and often continue typing a couple a seconds after your fingers have stopped...

I must say this is really annoying (especially when you have colleagues peaking at your screen :( ...)

To compare, doing the same typing in an emacs window makes xorg use about 15%CPU...

In have the feeling that the problem gets even worse when I connect an external monitor to my laptop (a Dell using intel graphics)

I can confirm this bug on a Dell D420 with Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03) under Debian/Squeeze and on a Dell E4300 Intel Mobile 4 Series Chipset  Integrated Graphics Controller under Ubuntu Jaunty
