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):

Yes it is a high DPI issue, so if running above 100% scaling you get the issue. So if running a large monitor at 100% scaling you’re good to go. But for people on the road with a UHD laptop it’s a real pain!

Incorrect. It is a problem with small 4K screens where 4K is useless anyway. I have 27 and 32 inch monitors and these problems do not occur. Adobe has important things to work on, wasting their time fixing user caused problems like this is not valuable to the majority of the user community.

This seems to be the problem with all window users with 4K screens. I’ve been dealing with this bug for 2 years now. Multiple versions of Lightroom later and it’s still not fixed. They have known about this for 4 years and done nothing to fix it. As more and more people upgrade to 4K monitors hopefully they will decide to resolve it. It’s extremely disappointing this still hasn’t been addressed.

I am using a Dell laptop with the monitor resolution displaying at 4K (3840x2160). The problem I am having in Lightroom Classic is the crop level tool and the white balance selector pipette do not align with the image on the screen.

The crop level tool is not a real problem because I can use the icon top knob as the reference.

However the white balance selector pipette is a problem. I have to set the tip of the pipette on the desired area and then drop straight down until the color appears in the view box. Usually the area I am sampling is small and problematic to find and center.

I wonder if this is an isolated problem with my computer or if this is a bug appearing in all 4K resolution monitors?

Any feedback is appreciated.

How is it even possible that Adobe knows about this problems for years now and isn't able to fix it?

This is very funky stuff indeed, i really don^t knwo how Adobe is not able to solve this problem or at least find a workaround.....
I work with Lightroom 1.0 till now, all paid and registered software version and now that...

On my Lenovo P70 with 3840x2160 Monitor i cannot solve this problem with changing screen scaling, eyedropper tip is always offset if 100% or 350%.
It does not change either idf i change schreen resolution to 1920x1080 or even lower

Boring!

I found that the better workaround for this problem is not changing the resolution of the screen but changing to a smaller value for scaling. The default setting of my Laptop was 200%. I changed it to 175% (the next smaller value) and now it works. That of course means that EVERYTHING on your screen will appear smaller. I've pretty much gotten used to that now. It's crazy though how one bug in one programm forced me to change my entire PC experience.

Same problem here with a HP ZBook 15 G5 (4k display) in Lightroom as well as Photoshop (worse in Photoshop as not even the normal mouse pointer works the way as it should as long as i don't drag the whole program to a HD screen or downscale the built-in screen to HD - then it works like a charm).
This is really a huge disappointment for a product targeted at professionals (I'm freelancing as a visual storyteller and have to rely on Adobe products) which are increasingly using 4k screens. How is it even possible that Adobe knows about this problems for years now and isn't able to fix it?

I have the same issue now that I upgraded my PC to a matebook x pro with a 3000x2000 screen. I'm still using LR6. If I set the resolution to 1920 in width I can use LR withouth the issue. It's a real bummer though because I chose this laptop because I thought the extra resolution would come in handy when editing my photos. Glad I haven't spent money on any other adobe software so far. It boggles my mind that they have known about this issue for three years and have done nothing to fix it.

Just upgraded to a 4K display with my home built PC running WIN10 and at that resolution I get this issue too. Drop down to 1080p and the dropper works perfect. Incredible that this hasn't been addressed yet.

I guess there just aren't enough LR folks using high-DPI Windows devices* to make it worth their time & effort.

</sarcasm>

*Increasingly, this is most Windows devices, I suspect.
