Description Sebas 2018-04-19 21:41:26 UTC
Pressing either the right arrow or space bar, or whatever other way to call for next image...sometimes you get next image, but after a while it only scrolls the horizontal bar, and no next image anymore.

This report depend of the context to use : icon view, preview, table view, etc...

In other word, please be more explicit to describe this problem. A screencast of digiKam in action can help to isolate exactly where the dysfunction appear...

Thanks in advance

From thumbnails select preview.
A bar shows up at top.
I make the bar as minimal as possible for more overview and bigger main picture. Could this be made a preference?

Then start moving right on PNG's of 60-140MB. And that seems to be the issue. When moving quickly there is quite a delay in displaying it in the main part of the window. And sometimes it gets stuck, then you have to move to another image and move back. Is there a setting to increase caching? Implement a loading indicator might be helpful too.

This issue is about smart caching. Preloading the next x images from the current one to eliminate loading time. Is Digikam changed on this aspect? It feels a bit better now.
Comment 5 caulier.gilles 2020-08-04 16:25:42 UTC
yes, it is. And Maik has also fixed more cache optimization recently for next 7.1.0.

Hello Gilles,
It's been a while...
Hope you are well.

It seems to still be there to a certain extent, but it feels a lot faster/snappier than I remember. Good progress.
