Strange problem when using highlight layers


Recommended Posts

Hi everybody:

When I use a highlight-layer based effect (fade in-out as Wingnut suggested me here) I obtain the following warnings in the web console:

  • .Offscreen-For-WebGL-00000233101348E0]GL ERROR :GL_INVALID_FRAMEBUFFER_OPERATION : glClear: framebuffer incomplete
  • .Offscreen-For-WebGL-00000233101348E0]GL ERROR :GL_INVALID_FRAMEBUFFER_OPERATION : glDrawElements: framebuffer incomplete
  • .Offscreen-For-WebGL-00000233101348E0]RENDER WARNING: texture bound to texture unit 0 is not renderable. It maybe non-power-of-2 and have incompatible texture filtering

The case is that all my textures are power-of-2 (512x512 px indeed) so I'm very lost here.

Sadly I can't reproduce this behavior on PG, so I only ask for a clue on where to start to find for solving this bug.

Best regards.

P.S. I have running OK other apps using highlight layers. Only for your information, the offending code is using PBR materials.

Hiya PR.  Hey, did you recently update to Firefox 58?  If so, I think the core Gods are working on a solve... but...

perhaps... https://www.mozilla.org/en-US/firefox/organizations/

That's Firefox ESR... v 52.6.0.  Revert to it... if you wish, and at your own risk.

I saw those same "framebuffer" errors after I updated to FF 58.  I reverted to ESR, and things started working again.

At minimum, you need to REMOVE all plugins from Firefox 58.  Not just disable.  REMOVE.  Firefox 58 ONLY accepts plugins made with the webExtensions API.  Using the old plugins with FF 58... seems to give highly-unpredictable results.

*shrug*  Just a possibility.  More comments from others... coming soon, likely.
