Is this scrolling when you receive a new message or scrolling when you manually scroll the chatwindow with the mouse? It is both. The CPU load happens because of scrolling, not because of new incoming messages. I made an experiment. I opened a new large chat window and asked to send me some messages. I saw no lags and no high CPU load before the messages started to autoscroll the chat window. And I found another thing. The same lags and about 50% of CPU load appear when I try to change the chat window size. I now tried to switch to Compiz 3D desktop with XGL and the problem with scrolling disappeared (before that I used ordinary no 3D desktop). But when I change window size in any application I can see some lags and CPU load jumps to 50%. These lags are not very noticable so I am not sure if they were before. As for the scrolling problems in Kopete it must be some how connected with default desktop in Mandriva I now tried to switch to Compiz 3D desktop with XGL and the problem with scrolling disappeared (before that I used ordinary no 3D desktop). But when I change window size in any application I can see some lags and CPU load jumps to 50% just the same as before. These lags are not very noticable so I am not sure if they were before. As for the scrolling problems in Kopete it must be some how connected with default desktop in Mandriva This sounds like a gpu driver or Xorg performance issue (similar to the current nvidia issues with kde4). On my computer scrolling the chat window uses about 16% CPU with the vesa Xorg drivers (KDE 4.0.99, debian lenny) and it sounds reasonable as vesa renders everything using the CPU. @Dmitry: What CPU and GPU were you using at that time you had the problem? Does this problem still exist if you disable XGL ? I have Core2Duo E6550 and Nvidia 8800GTS 640Mb. I found the source of my problem and this was a custom skin for Kopete. I had changed the skin with the Compiz on. So I didn't notice that the skin caused the problem. Sorry, I should have reported this bug resolved long ago. |
