[Debian GNUstep maintainers] Bug#495373: Poor support for the xmonad WM; blank windows with the cairo backend

[Yavor Doganov]

Hi Michal,

Here is what the upstream GNUstep Back maintainer replied:

,----
| The log file looks like xmonad does not reparent windows, that way
| GNUstep fails to compute any window border size and guesses them
| (wrongly of course). Most likely they should all be 0.
| 
| But this should not result in an all black (or gray, as the original
| report states) window, rather I would expect some black borders.
| 
| Do you know of any way to find out about the selected window borders
| with xmonad?  That is about the only thing I could think of doing in
| relation to this bug report. You state yourself that the original
| problem is not reproducable for you.
`----

Do you have any clues about that?  I took a quick look at the source
code, but it's all Haskell...

It appears that the grey windows you get with cairo are unrelated to
this problem.  Can you try a GNUstep app with the cairo backend under
a different WM (such as wmaker or anything else that is convenient for
you to install)?  Thanks.
