Hmm that's an interesting set of errors. It's not obvious to me what the issue could be. @Lecrapouille what OpenGL driver are you using?

Lecrapouille commented 5 years ago

My config: OpenGL version: 4.3 (Core Profile) Mesa 13.0.6 GLSL version: 4.30 I have a fresh Debian 9.9 updated. Mesa 13.06 is a little old (2 years old) but this is not the problem

When I posted issue https://github.com/tangrams/tangram-es/issues/1980 It worked (I mean I saw the map). Now I just reverted to this commit d1e2f787ae01e3d7294673af26061527f17bc41a and its working back.

I'll try to do a git bisect. I'll give feedback later.

Sorry, I tried again and the bug disappeared. Since yesterday I have rebooted my computer. Probably the bug produced because I tried an experimental GitHub project messing my GPU or when I added the API key for the first time.

PS: I understand now what happened: I tried another github application and for using it, I add to export:

export MESA_GL_VERSION_OVERRIDE=4.5
export MESA_GLSL_VERSION_OVERRIDE=450

before launching it. Then I did not use a new terminal when I tried tangram-es. So the bug can be reproduced (of course in a new terminal these variables are no longer set and tangram workes well).

I reopen it, in case your are interesting by it, else feel free to close it.
