P: White dot in bottom left corner

[FeedbackCommunityMember]

Whenever I open adobe Lightroom for Mac there is a small white dot in the lower left corner of my Mac display. I freaked out the first time because even when I minimized the app it was still there. Thought I had a bad pixel or something. Terminating the app makes the dot go away. I even youtube'd recent videos of people using Lightroom and that same white dot is there. Anyone know what this is? Im assuming its a simple bug and am wondering if both Mac and windows users are experiencing the same thing. Appreciate any feedback. Thanks!

Could you post a screenshot of it?

Are you using the current version? I vaguely remember a similar issue to this in an older version. If you're still seeing this with LR 2015.10/6.10, please post a full resolution screen shot and the version of macOS you're running on. Thanks.

[J453]

OK. I see it on Mac in full screen mode. We'll have engineering take a look.

We are able to see it here in Mac on Full Screen but not Windows. We will file an issue on it.

I also have this issue using the latest version of Lightroom for Mac (2015.10). I thought I had a hot pixel. It disappears when I quit LR. 

[Cameron Braun]

Same here, 2015.10 release.

Same here both normal and full screen. Thought it's a dead pixel or something. It also disappears when I quit LR. 2015.10.

Interestingly, when my MacBook is plugged into my Apple Thunderbolt Display, the dot is still there, but it's not in the corner. It's about 3/4 of the way down, and about 20 pixels in from the edge. It does show up on a screenshot. Also, when moving a window on the desktop, it pauses on the dot as if there's another window there.

Jeffrey, any word from engineering?

[Mr. Dmitry]

Please fix the issue with the white pixel on the left bottom corner of the screen! I can see it always when the Lightroom is running (not only on the full screen). I even thought that my new display was defective and requested repair! So, it's serious issue that must be fixed as soon as you can!

[Mr. Dmitry]

In the mirror mode I see it on the same place in that configuration (on the left bottom corner).

[Mr. Dmitry]

2 months passed and so simple issue still wasn't fixed!

[defaultne43o3kgogx3]

Well, to be fair, it's not really so serious. Most people never notice it. It's a very minor visual issue.

The Lightroom development team(s) will surely have a TON of things they need to work on. I would not expect a fix before several months have passed.

[Mr. Dmitry]

If it causes false evaluation of display as defective then it's really serious and it brings valuable damage. But if you want to fix more serious issues first then fix Auto Exposure feature! It works wrong for years! 100% of images are overexposed after using this feature. It's so nasty to correct it manually EVERY time by so huge values like 1.00 or little less.

Auto Tone is not a magic wand. It does exactly what it's supposed to do, which is, roughly speaking, to spread out the brightness values in the image so that they occupy the entire range from black to white, while more or less preserving the ratios between values. This does sometimes result in a too-bright image, but that's usually because all the values in the image started out bunched up against the left side of the scale — meaning that the image was severely underexposed and lacked highlights.

It would be really hard to write a program that would with one click optimize every image so that it looks perfect to you.

[Mr. Dmitry]

Thanks for the detailed answer! But ACDSee can do that. And you at Adobe can't? You shouldn't just fill the full range if it works bad for 100% images. Find any different approach.

For example, you can perform this step in different moment. Auto feature makes a lot of other corrections (by the way, it does it perfectly). Maybe they interfere with what you tried to explain.

Sorry, I'm not an Adobe employee! I was just guessing how Auto Tone works. 😉

I just purchased a new MacBook Pro and when I began using Lightroom, I saw the same thing and thought I had a bad pixel, too.  It seriously freaked me out for a second until I realized when I closed the program, it went away.  But still, I figured such a big company could work out small problems like this.

[FeedbackCommunityMember]

I just noticed the exact same thing, googled, and found this thread. It seriously hasn't been fixed in three months?

[FeedbackCommunityMember]

Just noticed the same issue on a brand new iMac 5k and freaked out. Seriously, Adobe can't fix one little pixel? I mean, I get that doesn't really affect anything within the program, but making people think that a brand new display is defective is kind of a problem!

[FeedbackCommunityMember]

I have the same problem on a 2014 Retina iMac. Just updated Lightroom today and white pixel is still there, right in the bottom left corner. Annoying!

[FeedbackCommunityMember]

Same dead pixel panic. Jeepers.

[Mr. Dmitry]

It's so terrible that Adobe doesn't have bug report system, support and even enough developers... They released update today with the same issue!

[JohanElzenga]

Apparently there were more serious issues to fix first. People could not use the map module anymore, for example. Doesn't that sound a little bit more serious than a white pixel on the display that does not affect anything else?

[FeedbackCommunityMember]

Yes...I see the same thing...scared me...LR 2015.12
