Last modified: 2014-12-18 08:28:57 UTC
Please describe the problem: only scroll 5-10 lines per sec ? Steps to reproduce: 1. Open a large file with 9000 lines, it's cool to using Chinese text 2. Scroll the text, either keyboard or mousewheel or dragging scrollbar. 3. Actual results: It's VERY slow scrolling 9000 lines text in gEdit(only scroll 5-10 line per sec with full speed mouse wheel.). and with 100% CPU usage. But it scrolling fast in kwriter. and lower CPU usages. Expected results: Smoothly scrolling text. Does this happen every time? Yes, every time. Other information: to see attachment.
Created attachment 82581 [details] Sysprof with scrolling 9000 lines text in gEdit. Sysprof with scrolling 9000 lines text in gEdit. 100% cpu usage.
This bug seems to be a duplicate of http://bugzilla.gnome.org/show_bug.cgi?id=172099
I'm afraid it's not duplicate of #172099。9000 lines of Chinese characters is small, just a file with several KB. I think it's a problem of rendering Chinese.
Does it still happen with a recent version of gedit? I've never had this problem, but I rarely open Chinese files.
