Bug: Artifacts on EXR bounds

EXR-Sequence is causing artifacts (see attached file) when an VR Chromatics Abberation Effect is applied. The error disappears, when „Falloff Invert“ is unchecked in the effect’s options.

It is most noticable when the image is stacked multiple times, otherwise it is barely visible. It persists in Preview and rendered/exported.

Disabling GPU-Acceleration in the Project Settings solves the problem – but makes the effect unusable.
