From 705a6446b4301498b83789a19d81aed4e922548b Mon Sep 17 00:00:00 2001 From: "Juan A. Suarez Romero" Date: Wed, 14 Mar 2018 17:09:34 +0000 Subject: [PATCH] mesa: RGB9_E5 invalid for CopyTexSubImage* in GLES MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit According to OpenGL ES 3.2, section 8.6, CopyTexSubImage* should return an INVALID_OPERATION if the internalformat of the texture is RGB9_E5. This fixes dEQP-GLES31.functional.debug.negative_coverage.*.copytexsubimage2d_texture_internalformat.
