There is a problem with the filter

[gimecho]

I want to see only images of filters
The filter has only set up images, but files from other extensions are visible briefly when you move the run or folder
On the Xnview Classic, this didn't happen.
Please fix the bug or solution.

[xnview]

for images, XnView need to check first header of all files before to filter them
It's the same in XnView Classic
