Package: koules
Version: 1.4-16
Followup-For: Bug #412056
Attached is a patch that fixes this bug, and also a patch to fix the
-y option.
The code koules uses to detect the display capabilities is broken: if
the server reports supporting a 32-bit visual (such as ARGB), koules
blindly assumes that's the one being used. The patch modifies koules
to explicitly ask the server about the capabilities of the default
visual.
