From 7a1004df7313518c5a9edf272000c502a33b5b47 Mon Sep 17 00:00:00 2001 From: Luca Bacci Date: Tue, 14 Dec 2021 18:32:51 +0100 Subject: [PATCH] Remove WM_SYNCPAINT message handler It was added to work around what seemed to be an OS or graphics driver issue on Windows XP. The issue was not reproducible on Windows Vista anyway.
