Hello!
Some of my frames are getting black organic kinda glitch and I don't know why or how to fix it. Could you please help me investigate this? Please see the attachment and those black things all over the image.
This image has been color graded, and these glitches appear randomly on a single frame throughout the video.

Alright, I think I solved this!
This happens randomly on a clip that has been graded, where an alpha is set to a node and either the node that is giving the alpha or receiving is disabled.
I'm reporting this as a bug.

Nope. That wasn't a fix. I'm still looking for help to investigate this issue.

That looks to me like a GPU that's a failing, or maybe the driver for the GPU is not working. You need to tell us:
Which hardware (CPU, GPU, RAM, disk I/O speed)? What specific version of Resolve? What OS? What source file codec? What timeline resolution? What framerate? Which GPU drivers are installed? What format are you trying to render to?

I'd say overclocked / overheating GPU

SSD disk

I will attach the metadata of drone and camera here.
Timeline resolution is 3840 x 1606
Rendering to QuickTime H.264 resolution 3840 x 1606
Does this help us?

Is there actually a way to do that other than re-posting this with "bug" in the subject line? I didn't see a way to report a bug on their website last time I checked.

Did we get any update on this or is it just the issue of my GPU?
