Adjust crop causes very long delay while preview is rebuilt

I would like the debug PhotoLab logs to identify the exact timings with a single image. It will ease the troubleshooting. The procedure was described in the message #23.

Thanks

@gpailler: I won’t be able to get to it right away, but perhaps in an hour and half or so.

Don’t worry, it will take more than an hour and half to properly identify and fix this issue so you can take your time :wink:

@gpailler:
I uploaded the log file with your name in the ‘ticket #’ field to “http://upload.dxo.com/” using the DxO upload form.

I added a crop to a previously unadjusted photo (“P1340140.RW2”).
The first time I opened the Crop function, the image displayed right away.
Upon exit from the crop function, the image displayed the new crop immediately.
Initiating the Crop function the 2nd time took many seconds to go from all black with crop outline to finally seeing the image – perhaps more than 10 seconds.
The 3rd time getting into Crop the image showed not instantly but within about 1 or 2 seconds.
I went in and out of Crop function maybe 5 times from begin to the end of the logging.
Many ERRORS of the same kind show up in log file that I hope you can comfort me about by the time we’re finished with this.

(Added note1: I’ve found that this might even start to happen on the 3rd try, too, perhaps dependent on crop size and or position, and maybe happens for other tries than 2nd or 3rd crop-tries as well.

Added note2: I believe that once I get the black view with the crop outlines, if the image is not rendered by the time I exit crop, the wait time for rendering is reduced the next time by the amount of time I’ve been previously viewing the non-rendered black image in crop mode – so, the delay period does not seem to be reset each time I enter the crop function – altho if I change the crop position or size a particular way, that might reset the delay – I haven’t tested that but seems it probably would work that way since the black screen apparently can happen on any new crop shape and position)

Thanks for the details and the log file. We have created an internal issue and will investigate deeper.

@gpailler Great to hear and many thanks :grinning: :+1:

@gpailler: By the way, is it possible that this other issue I have might be related?

Hello @BBT I don’t think the issues are related but we need to investigate this alignment issue too.
