From 8c2b816fc5bf9d30138ac068d1665e473c7cb4bf Mon Sep 17 00:00:00 2001 From: Sebastian Krzyszkowiak Date: Wed, 24 Oct 2018 16:37:48 +0200 Subject: [PATCH] SDL: set a hint to not bypass the window compositor Without that, window effects in KWin get suspended as soon as any qemu-sdl window becomes visible. While the SDL default makes sense for games, it's not really suitable for QEMU.
