From 9c063468d6b806de954d867ced857395c6162b82 Mon Sep 17 00:00:00 2001 From: "Ryan C. Gordon" Date: Sat, 24 Apr 2021 19:47:10 -0400 Subject: [PATCH] x11: call XSync before XSetInputFocus during SDL_ShowWindow. This only happens when using a non-NET_WM window manager, as we might try to set the focus before the window is mapped.
