I have a number of videos using the Turbulent Displace effect. Suddenly all my projects have a broken effect, even older ones that rendered successfully just one week ago with version 25.2.3 (build 4). 
 
Basically, applying this Turbulent Displace effect to a clip now causes the clip to jump around and resize as the effect parameters are changed. Also, all the edges of the clip are 100% digital noise/distortion. I tried deleting all the cache files to no effect. Loading old projects now have the bug during scrubbing, not just during render.
 
I reverted to 25.2.3(4) and everything is fine. I'll stick with this version for now.
 
The attached image shows the settings for the clip and the Turbulent Displace effect. Some parts of it are fine, but as the clip progresses thru the keyframes for Amount and Evolution, it starts randomly glitching and misplacing.
I did not change my video card (4070 Super) drivers related to when this problem started.
