From e6a693c447213b578f562edad8f15ccc43056acd Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Wed, 12 Oct 2016 14:01:34 -0400 Subject: [PATCH] st/mesa: only flip stipple pattern for winsys fbo's MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Gallium is completely oblivious to whether the fbo is flipped or not. Only flip the stipple pattern when the fbo is flipped as well. Otherwise the driver has no idea when to unflip the pattern.
