Bug 2865

Summary: SDL's EGL code doesn't properly support OpenGL ES 3.0 and 3.1 contexts
Product: SDL Reporter: Alex Szpakowski <amaranth72>
Component: videoAssignee: Sam Lantinga <slouken>
Status: RESOLVED FIXED QA Contact: Sam Lantinga <slouken>
Severity: normal

Version: HG 2.0

Description Alex Szpakowski 2015-02-03 05:36:28 UTC 
SDL's EGL code (used for OpenGL ES context creation on Windows / Linux / Android / etc.) only seems to properly support OpenGL ES 1 and 2 contexts.

In particular, the current code sets the EGL_RENDERABLE_TYPE config attribute to EGL_OPENGL_ES2_BIT if GLES2 is requested and EGL_OPENGL_ES_BIT in all other cases. It never uses EGL_OPENGL_ES3_BIT / EGL_OPENGL_ES3_BIT_KHR even when GLES3.0+ is requested. It also doesn't use EGL_CONTEXT_MINOR_VERSION_KHR to set the version to 3.1 rather than 3.0 in SDL_EGL_CreateContext, when 3.1 is requested.

Marking a large number of bugs with the "triage-2.0.4" keyword at once. Sorry if you got a lot of email from this. This is to help me sort through some bugs in regards to a 2.0.4 release. We may or may not fix this bug for 2.0.4, though!
Comment 2 Ryan C. Gordon 2015-04-07 04:57:59 UTC 
(sorry if you get a lot of copies of this email, I'm marking several bugs at once)

Marking bugs for the (mostly) final 2.0.4 TODO list. This means we're hoping to resolve this bug before 2.0.4 ships if possible. In a perfect world, the open bug count with the target-2.0.4 keyword is zero when we ship.

(Note that closing a bug report as WONTFIX, INVALID or WORKSFORME might still happen.)

This should be fixed with https://hg.libsdl.org/SDL/rev/6027a65e8528 .
