Hello,
Here is a patch that fixes a weird semi-transparency issue some apps
have when using cwm with a compositor. The issue seems to be that the
highest significant byte of the color is not initialized.
According to xwininfo alacritty has a depth of 32 and xterm has a
depth of 24. When using a compositor the windows with a depth of 32
don't have the proper border color.
I attached two screenshots to illustrate the issue. In cwm_colors1.png you
can see an alacritty window between two xterms. The active border is
orange the inactive blue. Alacritty has a white semi transparent border
when it's supposed to be blue.
In cwm_colors2.png alacritty is now the active window and it's now
slightly yellowish and semi transparent instead of orange.
The same issue happens with all windows that have a depth of 32
(firefox, thunderbird...).
Thanks!
Julien
