GNOME Bugzilla – Bug 553997
screen gets scrambled when allocation is bigger than scroll region
Last modified: 2008-11-03 21:55:34 UTC
when gnome-canvas' allocation becomes bigger than what was set as gnome_canvas_set_scroll_region, then the graphics become scrambled. unfortunately it seems to not happen on all systems. I use gnomcanvas 2.20.1.1, nvidia, compiz and opensuse.
Created attachment 119447 [details] standalone test app - move the square around with the mouse - resize the window, so that the scrollers disappear - move the square report what gfx-chipset you use
Works for me with and without compiz using this configuration: - x86_64 mode - same gnomecanvas version as you - xorg 1.4.0.90 (ubuntu hardy) - nvidia binary driver 177.13 (beta) - GeForce GTX 280
I just rebuild libgnomecanvas myself to /usr/local and to my suprise it also works fine then. Could be a gcc bug perhaps.
Some more investigation. The bug happens with libgnomecanvas-2.20.1.1 (latest released) but now with svn trunk. Getting a libgnomecanvas-2.20.1.2 would be sweet.
Stefan, feel free to make a libgnomecanvas release. Unfortunately I don't have time to cook one these days :(
The link on pgo was meant to be caught by distro maintainer who can at least patch their versions. Sven already agree that there will be new release for next gnome (2.26). Closing, as its fixed in svn.
