GDK W32: Don't use WM-drawn shadow for tooltips (1.37 KB, patch)
2015-12-27 05:11 UTC, LRN 		committed Details | Review

Description LRN 2015-12-27 05:11:48 UTC 
It's because the shadow does not come from Adwaita, it's drawn by
the WM, because tooltips have CS_DROPSHADOW class style.

GDK W32: Don't use WM-drawn shadow for tooltips

This prevents WM from drawing shadows around tooltip windows,
which, in Adwaita, should have no shadow and are CSD-ish (which means
that tooltip window is larger than it looks, and WM draws the shadow
only on the outside, leaving a gap between the visible tooltip edge and
the shadow).
Comment 2 LRN 2015-12-27 05:14:17 UTC 
Note that this will remove shadows from non-CSD-ish tooltips (such as when desktop composition is off). Not that anyone cares.

I thought about disabling shadows on a per-window basis, but CS_DROPSHADOW is a *class* style, it will affect *all* tooltip windows made by a given GTK process.
