From 616f285a074869fd79bc26509a0bd50e6e04e39d Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Tue, 9 May 2017 12:48:39 +0200 Subject: [PATCH 10/13] vga: fix display update region calculation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit vga display update mis-calculated the region for the dirty bitmap snapshot in case the scanlines are padded. This can triggere an assert in cpu_physical_memory_snapshot_get_dirty().
