From 7551f01bd0ed1ac6a82663305bc2dfe9bc07d034 Mon Sep 17 00:00:00 2001 From: Henri Verbeet Date: Wed, 27 Mar 2019 15:28:31 +0430 Subject: [PATCH] wined3d: Do not take "draw_rect" into account when comparing attachment sizes in ffp_blitter_clear(). The scissor rectangle and viewport shouldn't affect whether attachment sizes are equal. The Intel i965 driver will do a fast clear when the scissor rectangle overlaps the intersection of the attachments, and that behaviour is allowed by the OpenGL spec. This commit fixes failures in the d3d8 and d3d9 depth_buffer_test() tests on the Intel i965 driver. See also commit 0530f33cc1644cd782ee2028966721bddf28c5d4.
