Hi,
Browsing a library of images on my LibreELEC instance is abysmally slow: Opening a folder (with like 200 images) takes a minute, getting the thumbnails to show up takes minutes, not seconds. Playing .MOV files doesn't work at all, the screen blacks out and only the audio can be heard. (However, if I press "Back" on my TV remote I can see moving video in the background 
) TV remote response lags like 20 seconds.
I use a Raspberry Pi 3 with LibreELEC 9.1.002 running Kodi 18.3. The picture files are nothing special, most are around 1-2 MB in size.
I try to access my pictures stored in a folder structure on my NAS using SMB. It's the same SMB share used for accessing movies and TV shows on the same RPi machine; that works perfectly 
.
If I run the latest Kodi on my Windows machine and access my NAS with the same SMB protocol, I have no issues---pictures are appearing fast as they should. So it appears to me the problem has to do with LibreELEC itself.
Checking /storage/.kodi/temp/kodi.log I can see things like:

Any ideas, what could be the problem?
