material flipbook broken in 4.11?

Hi, i’m trying to create a flipbook based caustics material in 4.11 preview (always latest), my material animates smoothly in the material creation window but when i play the scene it glitches and jumps and is totally unusable. Is this a known problem?

Hey! I have the same problem in 4.10.4 when I use Perspective camera (Artifacts). Check please, will your game works better with the orto-camera.

I cant see anything of my scene in ortho view.

Is your tearing issue anything like this one here?

It’s not tearing i have, my flipbook texture is 60 frames for an animated water caustic effect, in the material editor its lovely and smooth and animates properly, in the scene it seems to play a few frames then jump to random frames then back to the start…totally unusable.
