Image Comparison : In Alpha Animation, dialogs hang winmerge #2370

Closed meteorquake closed 3 months ago

meteorquake commented 3 months ago

In an image comparison if you have Alpha Animation on and try to pull up Options (clicking the button), winmerge hangs. Also Help - About does, so probably a general problem with dialogs trying to pop up. Let me know if problem replicating and I'll provide full settings used. 2.16.40.0 W10 X64 David

I couldn't reproduce the issue with versions 2.16.40 and 2.16.41 either. Are you comparing very large images or something?

meteorquake commented 3 months ago

One image is 7.85 Mb JPG, 4896 x 3672, and the other is a 50%-quality JPG version of it that I was comparing for blemishes. So that would make it large - there wasn't a problem with alpha animation off, just when it was on, and waiting didn't appear to help - the animations themselves were fast enough anyway

Can you reproduce this with other image files?

meteorquake commented 3 months ago

I'll try a very small file and report back.

meteorquake commented 3 months ago

Just had a look - I can confirm it wasn't a problem with a small crop from the image, so it is likely related to file size

sdottaka commented 3 months ago

Thanks for checking, I think I've managed to reproduce the issue, I'll take a look at it later.
