You're absolutely right about .|. (Didn't bother to change it back then, as I knew that only the color bits would be set) The patch now looks like this: --- XMonad/Main.hsc 2013-01-01 02:31:47.000000000 +0100 +++ ../xmonad-0.11-fixed/XMonad/Main.hsc 2015-01-05 09:03:50.659161937 +0100 @@ -116,8 +116,8 @@ { display = dpy , config = xmc , theRoot = rootw - , normalBorder = nbc - , focusedBorder = fbc + , normalBorder = nbc .|. 0xFF000000 -- fix invisible borders + , focusedBorder = fbc .|. 0xFF000000 -- , keyActions = keys xmc xmc , buttonActions = mouseBindings xmc xmc , mouseFocused = False At first I was also worried that this might cause crashes, but haven't noticed anything in several months of daily use.

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)
