Bug 128145 – Mozilla Thunderbird 1.5: Scrolling is very slow

• Product: Gentoo Linux
• Status: RESOLVED WORKSFORME

[Description Magnus Rosenbaum 2006-03-30 10:58:35 UTC]

Scrolling is very slow and unsmooth. CPU Usage jumps to 100% when scrolling. Did not have this problem with Thunderbird 1.07-r3 und before.

Hardware is a Apple iBook G4 1,33 Ghz.


ibookg4 ~ # emerge -pv mozilla-thunderbird 

These are the packages that I would merge, in order:

I can't reproduce this on my PB G4 1.67.  Are you sure that you have X setup correctly and that you're not using fbdev?

[Comment 2 Jory A. Pratt 2006-04-19 17:54:49 UTC]

Works fine for me as well on G4 ibook.
