Does this happen if you enable the metacity compositor as well? It looks like matlab is foolishly using an ARGB pixmap with full alpha set which would work fine without compositing but gives the result shown when things start caring about alpha.
To enable metacity compositing run gconf-editor and change the /apps/metacity/general/compositing_enabled setting. ** Changed in: compiz (Ubuntu) Status: New => Incomplete -- Problems with matlab when compiz is activated https://bugs.launchpad.net/bugs/485792 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
