XnView Software

In the original thread user0 also could reproduce the bug, the dropbox links are still working.

They are still functional in the closed thread. By copy-pasting the links from the closed thread they got cut off midway.

I'm not sure if the additional problem was missed due to closing of the original thread, so I'm opening up a new one and link to it. I did also open a thread previously in the 'Reproduced - TODO' category over a week ago, with no traction ...

Version 1.8.7 improved on Lanczos4 and seems to be fixed, bilinear still looks blurry, but maybe that's just the nature of it. So far Lanczos seems to work fine so I'll go with it. But If I use Lanczos4 for 'Zoom in' in this version, there is a subtle image shift happening just about a pixel which ...

I also can confirm that version 1.8.6 doesn't improve on the bug as user0 already mentioned (at first I thought it was on my end again, but thank you for the clarification).

This is the original image (I'm sorry for ogling your eyes out :wink: ).

Using Lanczos4/Bilinear in different variations in 'Zoom in' & 'Zoom out' settings, if necessary I've already linked ...

I haven't seen that the update 1.8.5 has already been released, but I've tried again after I updated to this new version and it still shows the same problem.

I've cropped an example image here which is 8bit based:

So in the pursuit to get the bug in my thread fixed, https://newsgroup.xnview.com/viewtopic.php?p=203316#p203316
I've also linked the bug report here on it.

It seems they share a similiar problem about handling 8bit grayscale images incorrectly as mentioned by Pierre here and user0 on the solved ...

The new 1.8.4 version fixed the bug successfully, thank you again. But still is there some insight for the other linked thread's bug being connected to this topic? On second thought I seem to be affected by this bug as well, due to using the same kind of images.

Should I refer this solved thread to ...

I'm glad the bug was finally found and not an error on my side, thank you for bearing with me
On a sidenote, does this also affect the problem of the previously second linked topic due to the 8bit grayscale property?

I followed the steps to reproduce by creating a new xnview.ini config and changing the listed settings.

My new config does still not seem right. You are sure your folder thumbnail couldn ...

Yes, I'm talking about how the thumbnails of images inside a folder are blurry, while the thumbnail of the folder itself (using the 1st picture inside of it) is sharp and clear.

The catalog itself doesn't matter in this case, I've disabled it, the quality was still bad when I've downloaded the ...

Additonally to test it out, I've downloaded the imgur link and compared it to another image browser (Pictureflect).
https://www.dropbox.com/scl/fi ...

The thumbnail on folders in browser view mode looks clean and sharp (left) , while all the thumbnails of the images inside the folder are very blurry and unsharp (right).

I'm aware of settings as "sharpen thumbnail", "use embedded thumbnail" and few other managing settings such as the thumbnail ...
