XnView Software

XnView MP 0.98.1 64-bit
Windows 10 Pro version 20H2

Pictures are extremely pixelated when opened in full screen from file explorer.

Effect: display glitch

To reproduce:
1. Open the attached bugged.png from file explorer, so that it opens in full screen.

Actual behavior: the image is a pixelated mess, as shown in the screenshot fullscreen.png

Expected behavior: the image is displayed correctly, like in the previous version.

I'm not able to pin down what triggers this.
* It happens with most but not all images. I've attached fine.gif that doesn't trigger the issue.
* If I use the mouse wheel to switch to another image, then back again, it displays fine.
* With my usual settings, simply switching Settings - View, High zoom quality: Zoom-out & Zoom-in, to Bilinear makes the problem go away.
* If I start over with fresh settings, then there's no issue with non-bilinear zoom, so the problem must lie elsewhere. I have too many custom settings to start over, or to determine which one is at fault without some guidance.

Thanks to your detailed description I can reproduce the problem.

Thank you for tracking it down and fixing it so quickly in the upcoming version

This problem is supposed to be fixed in XnView MP 0.98.2. Please check and confirm the bug fix here.

* I can no longer reproduce the issue with the aforementioned image in full screen.
* Images (including the one in the original report) look pixelated at 100% size in the preview pane.
* Other images are still pixelated in full screen. I've attached an example.

In Preview of browser? You click on this picture, and you have the problem?

Sorry about the very late reply. In 0.98.4 all aforementioned issues appear to be gone. Thank you very much.
