X-Git-Tag: v9.0.0317
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=b13d3405fffae1115acc1433479b616f30e292e5;p=vim

patch 9.0.0317: when updating the whole screen a popup may not be redrawn

Problem:    When updating the whole screen a popup may not be redrawn.
Solution:   Mark the screen and windows for redraw also when not clearing.
            Also mark popup windows for redraw.
