I believe I have a similar problem. The sampler simply isn’t working. I select blue has the BG color and it selects orange. Then I clean BG and it just starts taking our random colors. I clean FG and it seems to be just selecting random colors.
I have been able to get around it by turning off the video card. Or more specifically setting it to software playback only in the project settings. Not a long term solution as I don’t get the power from my video card but at least it plays. I’m on newest model I’m at with the four gigabyte video card. I have the same problem on my Mac Pro running I GeForce 680 Mac Edition
I am having the same problem. I scale my 4k footage to 50%. When it’s paused, it looks fine. But it goes back to 100% when I hit play. When I export it it looks fine though. It’s impossible to work with like this. Any solutions?
I was having a stacking problem and all the proposed fixes didn’t work. After some tests, I found that If you have a floor plain that intersects with other objects, this can cause them to render out of order!
