[Gimp-user] images breaking up when zooming, and artefacts when using tools

2013-01-21 Thread phani
i've got a strange problem: when zooming images in the GIMP (2.8.2,  
installed from archlinux [extra]), viewing them  larger than the size they  
are being automatically zoomed to by default, they break up into  
unconnected, rectangular tiles.


moving (panning) them around with the mouse so that they partially leave  
the screen brings those parts back to be displayed properly. means i have  
to 'swivel' the image across all borders to get it to display properly.


in addition, applying scissors or path tool leaves artefacts on the image  
that can be removed the same way.


i've noticed this first with the development version of GIMP (2.9,  
compiled from GIT) and thought those were the new GIMP's growing pains --  
but then i noticed the same happening with the stable version (2.8).


i've tried switching to an earlier version of xf86-video-ati and to an  
earlier kernel, but neither rectifies the problem. i also tried different  
options in /etc/X11/xorg.conf.d/ 20-radeon.conf, whith the same result,  
i.e., none.


seems to have something to do with the image being refreshed, or not being  
refreshed, but which part of the system is at fault baffles me.



i'm using arch +testing, and here are my system's details:

System: Host: laptop Kernel: 3.7.3-1-ARCH x86_64 (64 bit) Desktop: KDE

there wasn't any reply, but i got the solution on the archlinux users  
list: after downgrading cairo from 1.12.10-1 - 1.12.8-2 the problem's  
solved. just in case somebody else runs into this and looks here...
