1.16.4 on Windows 11
As the subject line says, this isn’t a problem - I’m just curious.
When I first click on a thumbnail in the file browser (just to select, not open*), it takes a second or two before the highlight shows up on the thumbnail border and it’s visually selected. If I select another image and go back to the first, it’s instantaneous. If I go to yet another “first-time selected” image there’s a slight delay again. If I open an image in the editor and then click from image to image using the arrow buttons, the images I’ve opened are thereafter quick to select in the file browser. So thunbnails are quick after their first selection.
This happens only with raw images, though (at least my CR3). TIFs, JPGs, etc., are always quick.
I’m guessing something is initially loaded each time and thereafter cached, making it faster on subsequent selections. The “caching” doesn’t persist between sessions, though. I wouldn’t think the actual thumbnail image is the culprit since it’s already loaded. EXIF should be quick to retrieve, right? Or is something like exiftool / exiv2 being invoked each time?
* The only actual functional impact is when I open an image for the first time. Simply double-clicking doesn’t initially work, since apparently the first-time delay blocks the second half of the double-click. I have to select, wait briefly, then double-click. Hardly the end of the world, though.
But that said, if there’s something I have sub-optimally configured and it can be ‘fixed’, please let me know. Maybe it’s possible to enable caching of whatever’s being loaded…?
My laptop isn’t a fire-breathing graphics dragon, but it’s a pretty new machine with an 8-core AMD Ryzen 7 5700U, an AMD Radeon Vega and 16 GB RAM. So (other than the cheesy little GPU it has), it’s quick enough for most work.
Thanks.
