Just playing around a little... I recompiled the gnome-system-monitor to test this issue, and I made it disappear just removing the references to the colormap in the 'interface.cpp' source file. It looks like the problem appears when trying to use an alpha channel.
BTW, why the gnome-system-monitor tries to change the colormap? Is it really neccesary? It is clear that the bug is not in the application, but whether it is in gtk, gdk, X or the driver, I cannot tell. Anyway, just for fun, I have written a tiny workaroud to avoid the issue (attached)... ** Attachment added: "Tiny shared library that avoids this bug." http://launchpadlibrarian.net/13121156/no_rgba.c -- strange graphics bug, window looks squished, wrong colors https://bugs.launchpad.net/bugs/208570 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
