This Effect Requires GPU Acceleration

[Neofilm]

This issue may be related to this issue I reported just prior to this: Font is Wrong in Titles

Recently when applying the VR Light Leaks transition I'm getting a red notification when previewing "This Effect Requires GPU Acceleration". I didn't use to get this. I have GPU acceleration on though.

It only does this when I render clip before previewing (when there's a green line on the timeline):

The notification doesn't appear and the transition works/plays during preview perfectly when I don't render the preview. So, if I undo the rendered preview green line by changing the transition length then the timeline has a yellow line, notification goes away, and transition works.

However, if I put the transition back where it was and the timeline goes back to green then the notification comes back.

This didn't use to happen. This is a fairly new phenomenon. I hate paying a subscription fee for such a buggy program. Who has time for this???

Ok, so what seems to be the problem is this effect requires GPU Acceleration to be set when rendering a preview. If you render a preview with software only set and then rendered the project for preview this creates the problem even if you switch it back to GPU Acceleration it still shows the notification as if the preview is stuck in software only. So, I have to break the render by changing the file.

I was getting in the habit of rendering for preview in software only and again in GPU Acceleration to make the yellow line go away so this project would playback as smooth as possible. This is the only way to get the green line.

This seems to be the only effect that has this issue. Morph edit and color correction doesn't at least.

Why do you need to render: renderbar is yellow.

[Neofilm]

Because the project plays smoother when it's green. When it's yellow this means it may not play as smooth and in fact it does not play as smooth when it's yellow, red is worse, green is best.

Why not drop the screen resolution to 1/2.

Is your footage VR?

I'm having this same exact issue and I don't know what to do, there's a deadline and I can't export this without it saying GPU Acceleration etc. on the video......Anyone know what's going on?!?
