Thumbnails corrupted

[davidhelp]

Thumbnails are corrupted.
How to fix?

I tried Tools> Configuration> Preview> Thumbnails
I clicked on the Clear button on the right side where it says "Cache path: Thumbnails\

I clicked the OK button and I closed the folder then re-open and clicked on the thumbnail button I have on the toolbar or you can go to View> Views and choose the thumbnails size.

As you can see from the examples there are overlaps with other images or black spots where an image should be.

XYplorer 26.70.0500 - issue happened with last version. Same after update today.

With the images visible in the list:

View | Caches | Refresh Thumbnails

Thanks, that did not work. I also restarted after doing your fix and the one I posted.
The thumbnails were corrupted when I did a crop of the image then saved with the same file name and overwrote.
Not in just one folder but in others. If I press on the thumbnail the cropped image will pop up correctly.

Is there anything here I can delete?

Try changing the quality setting to various modes, then refresh using previous command I provided after each change, then swap back to orig setting if they are repaired,

Configuration | Preview | Thumbnails | Quality

But yes all those files are safe to be deleted, they will just get recreated when required, but you shouldn't need to.

Thanks, that fixed the problem.
I choose 'Smooth' then clicked on the Apply button then I cleared the cache above again then clicked OK then I saw the default icons for the picture viewer I use which is Irfanview then I pressed the F5 key which refreshed the thumbnails and now I see thumbnails that are the proper image.

That should not happen, and it does not happen here.
