P: White balance dropper target location is offset on high-DPI Windows devices

There appears to be a bug affecting all recent versions of Lightroom on high-DPI Windows devices. It affects both CC and standalone versions, up to and including the current version (2015.6.1).

The issue is that when using the white balance dropper tool in the Develop module, the target location Lightroom uses does not correspond exactly to where the point of the dropper is located. Specifically, it seems to reference a position about 5 or 6 millimetres above the point of the tool.

The issue also affects the manual defringe dropper in the Lens Corrections panel. Other local develop tools seem not to be affected (brush, spot healing, HSL/Color/B&W picker, etc.).

To be clear: the issue affects Lightroom when the device is used in standard desktop mode with a regular mouse as the pointing device. It is not an issue with the touch screen, the pen or Lightroom's touch mode.

The problem is described in detail with screenshots here (in the original post and in my reply):

So, when are you going to fix this? How hard can it be?
The problem also applies to the straighten tool in crop & straighten.

So, more than three years since this was officially logged as a known bug.

IS IT REALLY THAT COMPLEX, FOLKS, OR DID YOU JUST BLOW IT OFF?

In Lightroom, when setting White Balance, the eyedropper cursor inexplicably selects an area which it is neither pointing towards nor touching.

Why doesn’t it select something in the same manner as would an actual eyedropper -- at the very bottom tip -- as it does in Photoshop?

Rikk, I‘m really disappointed that this issue isn‘t fixed (again in LR8) for meanwhilst two years even though you were able to reproduce the bug!
In my opinion you should really listen to the pro and semi pro users and their performance and usability issues using high end equipment.
It‘s just weird to use pro software and have to guess where your mouse pointer is picking white balance, or where the ruler for the upright mode will be placed...

Just updated to the new version.

Still no change:

Lightroom Classic-Version: 7.3 [ 1164630 ]
OS: Windows 10 - Business Edition
Version: 10.0.16299
Resolution: 3840x2160
Scale 200% (my assumption is that LR can't handle this)

Any chance that this gets fixed soon?

When using a picking tool in lightroom 2015.12 on a 4k screen (Radeon RX470 video card) the mouse cursor isn't exactly where the functionality takes place (like picking a color or drawing a line to straighten the horizon line).

see screenshots below:

I think this thread can be merged with mine https://feedback.photoshop.com/photos... addressing the same annoying issue.
Somehow irritating that it’s still not fixed although LR representatives confirm that they can reproduce it...
