Hi,
since the 15.02. our nextcloud dont show good thumbnails.
Memories:
Photos:
On my Windows Client some images looks identical, some are ok
I disabled some apps, cleared the cache and previews, nothing helped.
Nextcloud AIO 28.0.2
System: Debian 12
No full Disks (58% free), no full Ram (20gb free)
Any idea?
Thanks
Is there a difference if you save the JPEGs in CMYK or RGB?
All are sRGB.
Today i tested the images on my Laptop and on the Laptop i have normal thumbnails on all new and old Photos. In the Cloud and my PC are the Photos are broken. Yesterday i saw too, that Screenshots on my pc make the same after upload in the cloud.
I have no idea, why this happen. The last App, we installed in the Cloud is gpoddersync. Before we didnt install an App for month.
Here is my Systemfile
