Hi,

I've built gegl and gimp from GIT sources. The speed of displaying a

Unfortunately, image updating due to scrolling or a redraw event  
scrambles the

image completely.

Is it only here (Gentoo Linux, bleeding edge, gcc-4.7.3) or is it a  
known bug?


You are probably suffering from a cairo issue, either too old cairo,  
or you

are running cairo with the xcb backend.



Many thanks, Michael! That solved the problem, indeed.
It's just unfortunate that I had to remove the awesome window manager  
since on my

(Gentoo) system, awesome needs cairo with xcb enabled.

Perhaps build a separate cairo for GIMP?

Anyway, here is the bug in case you are interested in the details:

Re: [Gimp-developer] image redraw broken with git sources

2013-10-03 Thread Elle Stone
I'm using cairo-1.12.14-r4 with use flags

 + + xcb: Support the X C-language Binding, a replacement for Xlib
 - - xlib-xcb   : Use XCB renderer backend for acceleration over xlib

Would things draw faster to the screen if I enabled xlib-xcb? Or would
drawing to the screen break?

cairo-1.12.16 is available in gentoo but masked. Helmut, which version
of cairo are you using? Mitch, what version of cairo do you recommend?

Just because it's a standard, doesn't mean it's right.

Hi Elle,

I use git master without any configure options except --prefix.

That's not really a recommendation, but it works for me :)
