[GEM-dev] gem bugs ?

[Georg Holzmann]

Hallo!

Just discovered 2 bugs (or at least strange behaviours):

1) 
create a gemwin, then close the gemwin with the mouse (clicking on the "x"
right above the window ...) -> crash (also if there is no gemhead ...)
the console tells me:

GEM: Only using 8 color bits
Direct Rendering enabled!
GEM: Start rendering
X connection to :0.0 broken (explicit kill or server shutdown).
pd_gui: pd process exited

for a gdb backtrace see below ...

2)
If I want to make a fullscreen Gem-window with [fullscreen 1( my window
manager (kde3.5) is really messed up ...
I don't know how to explain ... resolution is really low and if I move the
mouse I get out of the gemwin and see the rest of the screen (the patch,
console ...) in a really low resolution ...

I'm using Gem from cvs (compiled in january), pd0.39, xorg, debian, 2.6.14
kernel ...

LG
Georg
