I had some bad rendering issues (only on one project), but I was constantly given screens similar to yours, as well as “dots” would appear on other rendered frames. When I say dots, I mean it kinda looked like a dead pixel, but it would only appear for a frame or two, and sometimes there would only be 1 or two dots…other times they would be all over the place.
Anyway, the only way I managed to get this thing comfortably rendered, where I thought I had it all correct was to set my render speed to 1 frame a second. This was a 2 min HD project, with plenty of nodes, but Resolve was ripping through it so fast, you couldn’t even see some of the issues until I did a playback of the renders.
By slowing it down, It forced resolve to load the frame, then render the frame.
At one point I slowed it to 5 fps, but it still glitched out at some points.
1 fps seemed to work for me. Wouldn’t want to do it for a 90 minute feature however.
