From f9e9f7149027906785949d49b4e4c9b9ec896203 Mon Sep 17 00:00:00 2001 From: Sven Schnelle Date: Sat, 8 Aug 2020 21:56:29 +0200 Subject: hw/display/artist: Fix invalidation of lines in artist_draw_line() The old code didn't invalidate correctly when vertical lines were drawn. Fix this and move the invalidation out of the loop.
