If I rotate an environment with highres HDRI map (4k-16k) using RotX or UV transform it is very slow and updates every half second. Changing Power or other parameters results in same slow updates. In Standalone or in Blender plugin it is buttery smooth and view updates instantly.
Steps to reproduce:
1. Create an empty scene with HDRI environment.
2. Load a highres eg 8k environment file. eg from here: https://hdrihaven.com/hdri/?c=outdoor&h ... nk_farm_01
3. Try to rotate it or change any other parameter. The bigger the file the slower are the updates.
