gl: R/RG textures don't work on iOS
Last modified: 2015-04-11 17:18:01 UTC
+++ This bug was initially created as a clone of Bug #732390 +++ Currently only zeroes (i.e. green or black) is rendered when using them, while the fallback code path just works fine. Needs to be investigated.
This may be due to the slight differences between the GL_EXT_texture_rg and GL_ARB_texture_rg with respect to valid internal format parameters.
May be half fixed by: commit 48f8b5b46bae70477a59f615bdb075f02b7b90ac Author: Matthew Waters <matthew@centricular.com> Date: Sat Mar 14 18:45:01 2015 +0000 glmemory: fix the slight difference between EXT_rg and ARB_rg GL_EXT_texture_rg doesn't take sized formats for the internalformat parameter of TexImage* but GL_ARB_texture_rg and GL(ES)3 do. https://bugzilla.gnome.org/show_bug.cgi?id=732507
Where half means that the disabling of R/RG textures must be undone?
correct.
