Hello.
I'm trying display a weather radar loop as wallpaper. For that I create a .gif (or .mp4) file and update it every minute, however DF seems to cache the files, so any changes I make to the file it doesn't update on wallpaper.

Is there a setting or work around the cache?

Yes, that option is enabled. I suspect this option only affects when filename of active wallpaper changes. In my case filename stays the same, only file content changes.

So I've played around this and it seems DF scans folder only once:
Add a folder with a single file to the list, after DP showed the wallpaper from that directory, delete the file in that directory and add another file to that directory with different name. On next scheduled rotation, the wallpaper will not change.

Thank you!
It does reloads files now.
Just a little side effect: it blinks twice during reload, second blink is tiny, a second or two after first blink, but it doesn't loose position in the video. And it reloads video regardless if file was modified or not. It's not a big deal, however the DF is using 1% cpu during animation and it spikes to 40+% during reload of the video (gif), feels like unnecesary cpu usage if files not modified...

When it set to use a single image that is located on a network drive, DF refuses to update it, even after clicking "delete cache" button it still shows the old image. When I select folder where that image is, than it seems to update image just fine.
[EDIT]
Nope, using folder also has the same issue. It might be happening when remote computer is not available for a while, DF stops trying connect to it.

Single file on network drive still doesn't get reloaded.
