Markus Wick	8747f5fc0d	gl_rasterizer: Fixup for #1723. ... On invalidating the streaming buffer, we need to reupload all vertex buffers. But we don't need to reconfigure the vertex format. This was a (silly) misstake in #1723. Thanks at Rodrigo for discovering the issue. Fun fact, as configuring the vertex format also invalidate the vertex buffer, this misstake had no affect on the behavior.	2018-11-27 10:32:41 +01:00

ReinUsesLisp	8d4bb10d44	gl_shader_decompiler: Guard out of bound geometry shader input reads ... Geometry shaders follow a pattern that results in out of bound reads. This pattern is: - VSETP to predicate - Use that predicate to conditionally set a register a big number - Use the register to access geometry shaders At the time of writing this commit I don't know what's the intent of this number. Some drivers argue about these out of bound reads. To avoid this issue, input reads are guarded limiting reads to the highest posible vertex input of the current topology (e.g. points to 1 and triangles to 3).	2018-11-10 03:10:50 -03:00
