Version: (using KDE 4.0.2) Installed from: Gentoo Packages When i open text file in kwrite (kate too) scrolling is slow. If is document larger or if are more words on one page the text rendering is slower and slower and typing is very latered. THIS IS NOT COMPUTER OR DRIVER PERFORMANCE ISSUE. Configuration: AMD Athlon X2 3800, 4GB A-Data Extreme DDR2-800+, nVidia GeForce 8800GT 512MB etc... If i open same file in kde3 or GTK application rendering is fast. Same performance problem with page rendering in Konqueror, other browsers are fast.
Lots of changes have happened with scrolling in recent versions. An upgrade should make you happy. 4.1 should make you very happy. Can you try that and see if it helps? Thanks!
