0.94.2 High cpu load after viewing images

Subject: 0.94.2 High cpu load after viewing images

XnView: MP Windows
Version 0.94.2 64bits (Dec 20 2019)
Libformat version 7.36
OS: Windows 10 64bit

When I view images at the end of the folder, the cpu load increases to 20% and stays at 20% even after viewing images.

Effect: CPU load stays at 20%.

To reproduce:
1. Open folder ith many images (~3000)
2. View last image in full screen
3. Hold left arrow key for a few seconds.

Actual behaviour (bug): CPU load stays at 20% forever.

Expected behaviour: CPU load returns to 0%.

Additional information:
Directly after start XnView has high CPU, a progressbar is shown, but when it is done, the cpu load returns to 0%.
When I view images at position at start or middle (e.g. 2500 of 3000) no problem.
When I view images at position at end (e.g. 2900 of 3000) I have that problem.

XnView check other files in same folder, but not forever. Which formats do you have?
no problem when you open the browser in this folder?
