Error happened during GPU update

[tim.art]

Hello,

I changed a light shape "disk" to "quad" since I saw in the documentation it was unsupported yet, then I re-started the render and just got this error:

// Error: [gpu] an error happened during GPU update : Unknown error (Details: Function "bufferMap" caught exception: Assertion failed: "iter != m_map.end() : Non-existent property removed from graph", file: <internal>, line: 147) // 

That's not the first time I got this specific error -but on a different modification last time-, I've also changed the verbosity to debug but there is no additional information.

Edit: It happened again, this time I was switching between the lights display inside the Light Editor using the "Isolate" mode, then re-start the render and got the error.

Up, I'm facing this issue almost everytime when I switch between turn off / turn on lights in the Light Editor.

I just want to make sure you don't miss this issue, which is pretty bothering because everytime it raises I have to restart Maya.

Edit: If needed I can provide a scene.

Sorry, I meant to get back to you on this.

We have a repro for this in-house, so we've got an open ticket and we're working on it.

Thanks for reporting!
