Strangeness in HSL Shift panel

[Brad Brighton]

So...

I have an image that was imported from a PDF where I've been doing some color changes. When I first added an HSL Adjustment layer, all was cool. Left the tab open, went off, did other things... eventually back to the work at hand, double-clicked to modify, get the screenshot for the panel. Closing and reopening the editor panel does not change the behavior.

macOS 11.0.1 (intel MBP2018 15" 32G, 2.9 GHz 6-Core Intel Core i9, Radeon Pro Vega 20 4 GB, Metal enabled), Affinity Photo 1.8.6

A bug? Seems to be environmental in some fashion since closing the file and reloading from disk makes the issue go away.

ETA: This happened on a non-retina external display. I did not test whether it happened on the built-in display before reloading the file and the problem disappearing.

ETA 2: It has something to do with non-retina displays and/or moving the panel to the retina display causes a "corrective" redraw. Obviously, the condition re-occurred -- I moved the HSL edit panel to the internal display, the layout corrected itself, even after returning the panel to the non-retina external.

Hi Brad,

This is known to us. I'll give the bug a bump. Thanks for the reminder

Thanks for posting this. I'm glad I saw it. Now I don't have to restart to get the HSL dialog fixed... I can just move between monitors. I'm also on a dual monitor setup (MBP 16" over thunderbolt to Samsung C43J89x)
