Details
Description:
Bitmap font rendering in gtk applications is slow with Cairo 1.12.0-2. For example gvim and Dina (font) leads to slow buildup of the screen compared to qvim (qt) or gvim with a ttf font. The same problem also occurs for xfce-terminal, but not in urxvt. In htop it shows that xorg goes to high cpu load when making changes on the screen. With cairo-xcb 1.10.2 from AUR this problem does not occur, but cairo-xcb 1.12.0-1 from AUR does have the same problem. Additional info: Cairo 1.12.0-2 Steps to reproduce: Opening gvim with a bitmap font like Dina, shows a slow buildup of the screen. Also making changes like toggling NERDtree or adding or removing menu toolbars are slow. It is also visible when switching to a desktop with gvim open. The problem is more obvious when the app window is big. |

Are you using the ati or nouveau open source driver?
No, I use the nvidia driver.
there are already lots of bug reports about new cairo upstream.
please check if that has been talked there already or report it
there.
Ok, I will check the upstream.
