P: Refreshing crop view on secondary display

Hi.

My secondary display has a delay showing my cropped photo. If I crop the photo, LR Classic will refresh the second monitor only after I change something on the photo. For example, I crop the photo. The primary monitor shows the cropped area, but the second monitor shows the original area. If I change the crop area to whatever, the secondary screen updates and shows the previews cropped image (not the new crop). If I exit the crop tool, with the image cropped, the secondary display still shows the previews crop. If I change anything on the photo, for example, exposure by 0.1 (or anything else that forces a refresh), the second monitor updates the photo and shows the current crop. So, what I mean is that the second monitor is one step behind the primary display when showing the cropped image.
Besides, when I click the crop tool, the primary monitor blinks the photo very briefly and shows the previews photo I was working on, then shows the current photo again with the crop tool enabled.

PS: I'm using the latest LR version.

Any thoughts?

    I got the same bug after updating to 2020 version. Anyone else have this particular bug? I don't really feel like resetting all my preferences...But will if I have to.

    A Preference File will survive a Lightroom uninstall/reinstall. Sometimes weird behavior is corrected/cured by resetting the preferences.Reset Procedure:

    1. Close Lightroom.
    2. Hold down [Alt/Opt]+[Shift] while restarting Lightroom.
    3. Overwrite the Preferences when prompted by the dialog.
    4. Close Lightroom.
    5. Restart Lightroom.

    Does the behavior continue after resetting the preferences?

    Hi Rikk. It's not a delay. It's one step behind. If a change the crop and do nothing, the second monitor won't show the cropped version. Then, if I change something in the photo, it updates the second monitor the second monitor and show the photo cropped. It seems LR isn't refreshing the second monitor when I use the crop tool.

    I haven't reset my preferences. How do I do it? What do I lose by doing it?

    Thanks!

    The maximum delay I see on Mac is about a half-second. 
    How does that compare?

    Have you reset your preferences file?

    Thanks for the reply. I've turned it off, but didn't solve the problem. 😞
    I even restarted LR after turning GPU off, with no luck.

    I just read a similar report in another forum. This is probably a GPU issue. Turn off the use of the graphics processor in Preferences - Performance to see if that solves the problem.
