From e1762fb870f86afc4f6bd000b4a1c059d161f10d Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Mon, 8 Mar 2010 11:34:55 -0700 Subject: softpipe: zero-out entire clear_flags array in sp_tile_cache_flush_clear() Before, we only cleared the flags for the active tiles (the ones inside the framebuffer bound). The problem is if we later bound a different, larger surface to the tile cache we'd have some stale clear-flags still set (and mistakenly clear some tiles in the new surface).
