OpenGL error in electron 2.0.0

[itshaadi]

electron 2.0.0 was released yesterday and I tried it with mpv.js. everything looks fine but I get this Error message in my console. it doesn't seems to be affecting the player functionality but nevertheless it's an error.

os: windows 10_x64 build 16299
electron: 2.0.0

[11664:0503/170106.364:ERROR:texture_manager.cc(2437)] [.PPAPIContext]GL ERROR :GL_INVALID_VALUE : glTexImage2D: invalid internal_format GL_RGBA16_EXT
[opengl-cb] after creating texture: OpenGL error INVALID_VALUE.
[opengl-cb] Error: framebuffer completeness check failed (error=36054).
[opengl-cb] Error: texture could not be created.

getting the same error, but can't make mpv.js do anything on electron 2.0.2, the example doesn't work if updated.

Can reproduce it. Probably Chrome broken something in PPAPI implementation.

Though plugins seems to be working normally in latest Chromium.
Might be something electron-related.

Tested a bit more.

• Works fine with electron 1.x
• Shows error for electron 2.0.x
• Works fine with electron 3.0.0-beta.x

Seems to be either regression in Electron or Chrome 61. Does anyone know for how long electron 2.x is going to be supported? I.e. is it worth the efforts.

Might be related electron/electron#12937

Tested Chrome 61÷66, issue seems to be fixed somewhere between 64 and 65.

Found commit which fixes error: https://chromium.googlesource.com/chromium/src.git/+/37924baf9ac8f3ce7811508bc650efe965bb50b2^!/

Closing because it was fixed in latest electron/Chrome (3+/65+) and doesn't affect functionality.
As far as I can understand it happens because Chrome reports support for 16bit textures, mpv tries to create 16bit FBO and that fails, so it fallbacks to usual dumb mode.

There is one more issue which I thought was related to this one, but it seems to be happen only on Linux: electron/electron#13624

on 2.0.x ARM releases for raspberry pi you can fix this issue by enabling hardware graphics acceleration.
