Re: [xmonad] Fix invisible borders

4 Jan 2015

I should note that (a) this may not be completely safe for ordinary
windows, and (b) it still won't help programs that use DirectColor visuals;
both which might cause xmonad to throw an exception.

Cool, seems like a good thing to fix! (Personally I don't use borders,
though)
While this is fine if you can guarantee (nbc < 0x01000000 && fbc <
0x01000000), it may be worthwhile to use (.|.) from Data.Bits instead
of (+) to ensure that the colors don't overflow.

Hi,
I just browsed through the mailing list and noticed that some people
were having problems with borders disappearing when viewing RGBA
windows. This happened to me with Nautilus, Evince, Chrome and others.
I've written a tiny fix for this more than 6 months ago, but never
contributed it. (Didn't manage to install darcs. Just tried again for an
hour and failed again)
Thought I should post this in case someone is still suffering from it.
The patch flips the transparency bits in addition to the color bits
specified by the user.
(They are 0x00 otherwise and result in full transparency)
