Adjustment layer lag in photoshop since version 21.0.3 - including new version 23.0
This has been an issue for a while - the handles on adjustment layer properties not smoothly following your cursor, making it very hard to make precise adjustments. I've recorded some video s below to demonstrate - on curves layers as it's most pronounced there. This is on a complex file, on a high DPI PC screen (still apparent on a standard definition screen) but I've made it a relatively difficult example to make the effect as apparent in the video as possible.
Perfectly smooth in v21.0.3, horrible laggy on everything in v21, v22 and v23 since that release:
This is on an i9-9900k / Quadro RTX 4000 / NVME application drive, separate NVME scratch disk and backup scratch SSD / 64GB DDR4.
Same problem on a i7-6700 / GTX 1080 / NVME application drive, separate NVME scratch disk and backup scratch SSD / 32GB DDR4.
Same problem on a heavily specced 2018 15" Macbook Pro.
Tried every combination of settings in the preferences across all of them. Can't figure it out - it seems like something fundamental changed after 21.0.3 that's just killed adjustment layer performance.
