From 15a753b9a5b5cd08520c7ee78ea2a93d06f6b316 Mon Sep 17 00:00:00 2001 From: ReinUsesLisp Date: Tue, 17 Dec 2019 22:38:50 -0300 Subject: shader/texture: Properly shrink unused entries in size mismatches When a image format mismatches we were inserting zeroes to the texture itself. This was not handling cases were the mismatch uses less coordinates than the guest shader code. Address that by resizing the vector. --- src/video_core/shader/decode/texture.cpp | 13 +++++++++---- 1 file changed, 9 insertions(+), 4 deletions(-) (limited to 'src/video_core/shader/decode') diff --git a/src/video_core/shader/decode/texture.cpp b/src/video_core/shader/decode/texture.cpp index 994c05611..dff01a541 100644 --- a/src/video_core/shader/decode/texture.cpp +++ b/src/video_core/shader/decode/texture.cpp @@ -743,13 +743,18 @@ Node4 ShaderIR::GetTldsCode(Instruction instr, TextureType texture_type, bool is // When lod is used always is in gpr20 const Node lod = lod_enabled ?
