What are the potential causes of an asynchronous error in a WebGLRenderingContext?

While running an animation loop, I encountered a peculiar error message that reads...

GL ERROR :GL_INVALID_OPERATION : glDrawElements: Source and destination textures of the draw are the same.

This error seems to occur randomly after 2 or 3 animation frame requests, with no consistent pattern even after screen refreshes. Sometimes a hard refresh delays the error to the third request, but most of the time it occurs after the second request. This inconsistency hints at a potential issue in an asynchronous component. Despite simplifying the program down to just displaying a stationary cube, I have not been able to pinpoint the source of the problem yet.

The complexity of the program makes it difficult to narrow down the problematic code section here. Therefore, I am seeking guidance on how to approach such issues more broadly. Can you advise on the key areas of focus when troubleshooting this type of error? Once I understand this, I can better direct my efforts towards resolving similar situations in the future.

If further clarification is needed, please let me know. Thank you!

Update:

  • An interesting observation - removing all objects from the scene eliminates the error, suggesting a connection between object presence and the occurrence of the error.

  • I'm also considering if a lost context could be responsible for triggering such errors, as mentioned here.

Answer №1

To resolve your issue, it would be beneficial to share the code you are working with rather than relying on guesswork.

The error message is clear in stating that there is a texture associated with the current framebuffer that is also linked to a specific texture unit.

The intermittent nature of this problem may stem from asynchronous loading of textures, especially if they are being fetched from images or dataURLs. If textures are cached or loaded quickly during local testing, it can lead to inconsistencies. One potential explanation could be related to incorrect configuration of texture units each frame (ensuring proper usage of gl.activeTexture and gl.bindTexture for all textures used by shaders). Asynchronously downloading an image may trigger a call to gl.bindTexture, causing the assigned texture to match the active texture unit and disrupting the setup.
