Lightroom displays incorrectly sized images momentarily in Crop mode

Lightroom consistently displays an incorrectly scaled preview image occluded by the crop rectangle UI the first time you enter crop mode from an newly displayed / selected image.

This also happens switching between images while staying in crop mode.

The end result is extremely visually disruptive and also not present in other programs such as Capture One and Aperture - please ref the following video

I see the same thing on Windows. I can live with the sliders being disabled until they can be used because that is visual feedback of the state of readiness during the transition, but I do very much dislike the loading of the cropped preview instead of the full-res preview as a placeholder while things are loaded. It seems like LR is just using the wrong placeholder preview, though perhaps LR doesn't cache a non-cropped preview of the current settings, anywhere, so has to compute one, and if it doesn't cache this, then it should.

Windows Terminal-Services/Remote-Desktop has a ForceOffScreenComposition flag you can turn on so when viewing things over a slow connection you don't see glitches and flicker while the screen is built. Maybe LR needs to do this sort of thing--off-screen-composition, or at least have a setting allowing it.

Having it as a preference allows the user to tailor things to their needs: if the transition is too slow--imagine several seconds, then you probably need to see the display lurch into form to feel that things are actually happening, but on a relatively fast computer, having things seem to pause for a brief moment--during the time the sliders are disabled, for example--would give a smoother user experience, and No I don't want to see an hour-glass or clock animating in front of LR if it's taking several seconds, either, though it might be less disconcerting than seeing the image behind the cropbox change size.

Is there an "official" way to get this entered as a bug with an id# etc or is this just all anecdotal ?

Someone at Adobe supposedly reads every initial post, at least, and they probably pay more attention to the threads with higher +1 (me too) counts or many replies, and whoever it is that reviews these posts will decide, somehow, whether it goes further in the process.

You will know that someone at Adobe agrees with your assessment of there being an issue if it says Acknowledged, and if they actually are doing something about it, then it'll say In Progress. The lack of any statuses like those doesn't mean no one cares, it could just mean that no one has updated the status. It might also mean that the issue has already been addressed in the next version without it having been reported, here, so it's not linked to any internal coding task. Maybe LR6 has had the cropping area rearchitected and there will be different things that people find annoying. Who knows. Adobe is always looking for ways to speed things up.

In other words, while this is not an official bug list, it can reflect the status of the issue that has made it to the internal tracking system, with varying degrees of accuracy.

If you click on Problems at the top of this thread, you'll get a list of Common Problems and the top one is for LR4 and says In Progress. I would expect that something two years old about a previous version of LR has been either fixed or abandoned long ago, but not marked Solved due to incomplete synchronization of the internal and public lists of potential issues.
