Description Niels 2013-05-08 22:41:10 UTC

I often browse network folders with 1000s of images in them. Gwenview apparently tries to prepare thumbnails for everything. That's a kind gesture, but it kills my network and cpu, and isn't really needed. If I don't have the thumbnail bar open and I'm just flipping through images, I'd probably want next/prev image to be cached, but there's no need for 10.000 thumbs.

If I could just stop it (e.g. <esc>), that would be fine.

Reproducible: Always

Hi Niels,
would a config option like "generate thumbnails when no thumbnailbar/view is open)" also be ok for you?

Comment 2 Niels 2013-05-13 09:40:57 UTC

Hi Benni,

yes, I suppose it would. The important thing is that the thumbnailing process should stop, if it has started, when thumbnails are hidden.

Thanks.

Thank you for the bug report.

As this report hasn't seen any changes in 5 years or more, we ask if you can please confirm that the issue still persists.

If this bug is no longer persisting or relevant please change the status to resolved.

I don't have the same setup, but from a quick test with a remote ftp folder, it seems that Gwenview doesn't make thumbnails in the background when I view single images. So that seems to be a "problem solved". You're much more qualified to look at the code to check this behaviour, but from my end it looks fine.

The general problem of "does a program use too many resources with background tasks that may not be needed" remains open and is difficult to solve, but probably not relevant here.

It would still be nice to have esc stop generation of thumbnails in browse mode.

Thanks!
