Just did another test, and actually Cycles does not support any VSE time remapping, it just renders the nearest frame, so will render the same frame 3 times if the speed is decreased to 33% for…
I know very little about these things, but I don't see what other app than blender could modify the config folder content and reset it to factory mode.
Yes this crash happens when opening/switching to another scene inside a blend file. And it appears when using Flare wizzard, so I've reported to the developer. He said it might come from a bug in…
Another comparison on a 4K project, the difference is actually massive, GPU on my main machine with scale node:
And GPU on my…
Ok sorry in fact my scale workaround in indeed totally destructive, the GPU composited image is super destroyed if corrected by the scale-fit node:  Trigger: even if not saving + re-opening file,…
When selecting all bones in the 3d scene pose mode, before doing the render, I still have only the last spine upward that is bugged, but previously on that file it was the whole amature.. ![image]…
So clicking any bone, makes Spine_03+neck to head bones jump to last rendered frame pose, except the neck_02 bone that is not KEYED on that action, this one remains where it is at the real current…
So I'm trying to stab at the bug, doing a render (from another scene in the file, with pose mode active or not ect..), saving, closing, re-opening, and seeing if I could manage to identify…
@iss in case it helps, the latest occurrence of the bug was on that project I sent for the prefetch crash: https://projects.blender.org/attachments/35f1fcc8-40c9-4079-9e8b-210163acf7b3 On the…
@iss ah nice 84MB fits, and the crash still happens. (just go in the Video sequencer workstpace, and click prefetch on the n-panel of the video preview.)
@iss sure, I'll try right now to reduce the file size while making sure the crash still happens in a nearly empty file. (that I can paste here)
But in the meantime if you want, you can download…
Actually, I did bit more digging and found, that this probably has nothing to do with persistent data. But forgot to change status, because I need confirmation of my findings and new steps to…
Sounds like this is same issue as descrbed in blender/blender#42423 (comment) Can you check if this workaround works? @OmarEmaraDev do you…
Ok there might be a bug comming from blender, now that I got rid of any flare from Flare wizzard, the compositor, if opened in the FOG scene, systematically crashes blender.
So talking with Flare wizzard developer, there might still be a blender bug responsible for this crash. As when I reproduce it on a blank file, get one of these script execution popup, and allow…
