Dehaze Might Impact Upright Tool (and Other Tools with Zooming) Performance?

[yichenhu88]

Hello Everyone,

Yesterday I noticed that my upright tool in one of my photo became so unresponsive, that I couldn't move the guided lines properly (more than 5 seconds before it even moves when dragged).

I tried different adjustments and different RAW files from Canon, Sony and Panasonic cameras: I am now pretty sure that it's the "Dehaze" making the performance so bad and things would get worse as I add more guidelines.

Other tools with zooming (WB picker and Detail) would be affected as well.

"Clarity" might have a slightly negative impact but not half as bad as dehazing.

I am wondering whether it's something in the Camera RAW engine and affecting everyone.

I tried the upright tool in Photoshop and it works fine when dehazing was applied.

Thanks

Yichen

P.S. My Computer:

Ryzen 1700 + 24G RAM + GTX 1050 Ti

Both LR and LR Cache on an SSD

What happens if you apply guided upright first and dehaze afterwards? Seems like a reasonable work-around.

Well I know it could be a workaround.

But there's always a time that you want to adjust the parameters like WB again or make a duplicate to see differences; keep bringing dehazing back to 0 first is still pretty annoying.

I have to say I just realized that dehazing slows down the performance of adjustment brush as well... The "dehaze" in the adjustment layer might be affecting the performance as well, but not that badly; it's tolerable for me

Dehaze slows everything down, not just brushing.

I haven't updated the LR on my laptop so I just tried the older version (7.2): It wasn't half as this slow.
