Performance hit with Pattern Fill layers set at an angle

Hello,
Apparently many creators are aware of this issue (I saw TextureLabs complain about it on youtube among others), and I personally encountered it enough times. The performance hit seems to appear mostly on big canvases. more pattern fill layers = bigger performance hit. but if they’re at 0 angle, then the performance is fine. I don’t know if a smaller scale also contributes to it.

This is an issue especially because it limits the patterns I can create and use on photoshop as I feel forced to use patterns on 0° angle, but then, creating the pattern as rotated from the start makes it difficult-to-impossible to seamlessly fill the corners using photoshop only.

I don’t see why would the performance be impacted if the pattern is an angle more than what it would as 0. I don’t think any computations need to keep on happening once the pattern is displayed.
