Images very slow to display after selected in browser

[bcomer]

I have a folder with about 50k images - when selecting an image there is a long delay before it is displayed.
There is also a long delay after selecting the escape key to return to the browser list.

Version 1.8.8 on a Mac Studio M2U/128GB/4TB running MAcOs 15.4.1.


Any thoughts on how to speed this up?

When you open an image into an image tab, or when you select a thumbnail to display preview?

When I select an image it fills the main window.
