https://bugs.winehq.org/show_bug.cgi?id=42988 --- Comment #2 from Fabian Maurer <dark.shadow4(a)web.de> --- The problematic patch is 0001-ddraw-Implement-ddraw7_FlipToGDISurface.patch commit 08637d96be1c2a74106f92d13623313072100d73 Author: Henri Verbeet <hverbeet(a)codeweavers.com> Date: Sun Jan 8 22:32:32 2017 +0100 ddraw: Implement ddraw7_FlipToGDISurface. (v2) Reverting this patch in staging fixes the issue, applying this patch on vanilla introduces it. I tried both stable mesa and git (17.2.0 git-a5f82db380 / Mesa 17.0.5). The issue appears when using the Cinnamon desktop too, so probably not a Plasma bug. LIBGL_ALWAYS_SOFTWARE=1 does not help either. Also, I noted the issue seems to only appear if you go fullscreen (alt-enter) during or before the first video. So press alt-enter as soon as the black start screen turns into the "Pocket Mirror 2014/2016" splash. The flickering then appears, and stays even when going back to windowed mode. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
