XnView Software

I've tested a bunch of versions:
2.39 works great, no issue
2.40 has different problem, black background and white pixels on the border
2.40.png
2.41+ has problems with alpha sometimes visible, sometimes RGB, depending on zoom < or > 100%
Something got broken between 2.39 and 2.40

Attaching the ...

Could it be related to Windows?
I have the latest version: Win 10 Home, ver 2004, os build 19041.508

But I've tested an older version, 2.37 just now, and it doesn't suffer from the same problem.
So I think something got broken in your code.
It was working fine just couple releases ago.

Is there a ...

The problem happens with any/all images that have alpha channel.

It's broken 100%

No

In Options>General>Read-Wirte, you can choose your formats

I think I've explained it pretty clearly in the first post, that I want to HIDE all other formats.

In latest version 2.49.4

Please use any image that has alpha channel, BMP, PNG, TGA, any
Then set zoom to be less than 100%, for example 50%,
Then press M key to show alpha, it won't work

Zoom in at 100%, alpha starts to work

In options I have "High Quality Zoom \ Reduce = ON"

Latest release broke previewing images with alpha channels.
Press M to see alpha channel (show mask menu) doesn't always work, sometimes you need to press Ctrl+H first (Use Alpha Channel)

No

Is there any news about this?

Because this is a MAJOR inconvenience.

Also another BMP file format got added (565 bit quality). Things got even worse!
Several times accidentally I've selected it instead of the full 8-bit precision, and that resulted in loss of quality, because of which I had to ...

Just tried XnView MP for the first time, it looks cool, but the main problem compared to XnView classic is startup time.

XnView classic starts instantly for me, I don't see any delay.

when I try to run XnView MP there's a 1-2 second delay until the app opens.

I have a brand new laptop:
8th gen ...

Please add the option to hide other formats.

Because as it is right now, it's just a big inconvenience to have to scroll so much every time I want to save a file.

Thank you

When I want to save an image, and I want to choose target format, it's like 30 or so, making it very difficult to find the one that I need.
Having so many elements on the list is just an annoyance, because 90% of the file formats people will never use.

The only formats that I use are:
BMP
PNG
JPG ...

If I save any image as WEBP format, then always (0,0) pixel will lose its RED color data.

For example if (0,0) pixel is RGB (20,230,255) then after save+load of WEBP file, it gets (0,230,255) RGB (RED is lost).

I'm using XnView 2.32
