0000997: Information popups contain random pixel noise instead of text
Information popups contain random pixel noise instead of text.
To reproduce, start the IDE, open any C++ file and hover over any symbol. The information control that appears contains only pixel garbage.

Eclipse (4.6.1) exhibits the same behavior.

Before updating the OS, the correct contents appeared in a window in the top-left corner. This 2nd window never disappears, rendering the desktop nearly unusable.
No tags attached.

This appears to be a bug in the GTK3 browser widget. See also: Ubuntu menubar -> About this computer -> Legal Notice tab (same pixel noise).

WORKAROUND:

export SWT_GTK3=0

If you start the IDE using a desktop shortcut (.desktop file), prefix the valur for the Exec= line with 'env SWT_GTK3=0':

Exec=env SWT_GTK3=0 omnetpp
