P: Preset hover preview incorrect for Incremental Temperature / Tint

Hmm, I still see the misbehavior when Treatment & Profile is selected creating the preset.  Here's the preset:

John, I can confirm if 'Treatment & Profile' is checked when creating the WB Develop Preset with a JPEG file the rollover issue is no longer present. Also when applying it to a raw file it does NOT change the Treatment or Profile settings. That appears to be the easiest fix for now.

But I don't observe what you observe with changing the profile from Adobe Color and back. That's why I'm wondering if there might be something different about the preset.

I see the misbehavior with this sample Canon 5D MKII raw:
https://www.imaging-resource.com/PRODS/E5D2/E5D2FARI00050.CR2.HTM

But it's barely noticeable. Here's the Photoshop difference of the hover and non-hover previews:



I set the whitepoint in Levels to 10 -- thus, most of the differences in the red channel are 1, 2, or 3 (out of 255).

It is the same behavior as the original post.  When you hover over the preset everything looks normal until you select the preset and hover over the photo.  The photo turns noticeably more red.  

I checked it with CR2 files from Canon camera models 300D, 600D, 6D, and G9 X MKII and they all exhibit the issue! For some reason the Canon 5D MKII CR2 files don't display the issue. You can download 5D MKII CR2 files to test here: https://www.imaging-resource.com/PRODS/E5D2/E5D2THMB.HTM

I think you're experiencing a different bug, or some variant of the one reported above. For the recipe I provided, in my configurations, changing the Profile from Adobe Color to another profile (e.g. Adobe Monochrome or Adobe Vivid) and then back to Adobe Color restores the appearance to that after applying the preset and moving the mouse off of the preset, not to the hover preview.

Can you please right-click that preset to show it in Finder, then edit the .xmp in TextEdit and copy and paste the contents here?  I'd like to see what might account for the difference.

Your preset causes the misbehavior in my LR 8.4.1 on both Windows 10 and Mac OS 10.14.6.  So something else must account for the difference.

Created using a Canon 5D MKII JPEG file and applied to the same CR2 raw file shot raw+JPEG. Here you go:

I made a video showing where the Bug is.
