[Xquartz-dev] Line drawing in 1.5 and 1.6 servers

[Martin Otte]

Hi,

The problem with the lines not drawn correctly occurs when calling  
XCreateSimpleWindow. The program I have uses XCreateSimpleWindow to  
create the buttons and their borders. When I increase the size of the  
border in XCreateSimpleWindow and turn off all other decorations, this  
is what I see:

It is interesting to see part of the quartz-wm frame imposed on the  
button borders. My guess is that the border pixmap is not being  
created/shown correctly in the server. Looking through dix/window.c  
and mi/miexpose.c a lot has changed between the 1.4 and 1.5 versions  
of the server, so I don't think I'll be much help in tracking down the  
problem.
