Image copying fails to display

[alee001]

Every time I drag and drop two or more JPG images from File Explorer to my MP folder, one image always fails to display in the browser thumbnails (as shown in the image). I have to press F5 to update to fix it. Is there a problem?

P.S. Windows XnView MP, any version

Additionally, when searching for a folder using the quick filter, version 1.9.8 sometimes fails to display some thumbnails (as shown in the image above). Pressing F5 to update resolves the issue and displays all thumbnails correctly. (This problem did not exist in previous versions.)

1) I found that dragging and copying JPGs works fine under normal circumstances; the problem only occurs with JPG files saved from Photoshop.

2) When quickly filtering to find the folder I need, there are more problems when the folder contains a large number of files (over a thousand).

3) When a PNG image is converted to a JPG using Ctrl+U, the thumbnail cannot be displayed correctly. You must press F5 to update and it will be displayed correctly.

1) Select a PNG image and press Ctrl+C, then Ctrl+V to copy the image; the thumbnail doesn't display.

2) Press F5 to update and it should display correctly.

3) Select the copied PNG image and press Ctrl+U to convert it to JPG; the thumbnail still doesn't display.

4) Press F5 again to update and it should display correctly.
