Thank you very much for your hints. I have made some trials and have gone through your suggestions. I have two OH-systems running.One is OH4.3.x running for my home since version 2.8 where I have never had such behaviour. The new system OH5.1.0.M3 is for a different project an is running on Raspberry 5.And as I just said, the issue is dirctly appeared after upgrade from OH5.1.0M2 to M3. Before all worked fine.
- new SD-card doesn’t change anything
- all images are correct in the indicated folders, also moving into static/ directly dosn’t solve it.
- finally the solution was that I had the path in the cards “background image” line defined w/o the slash at the beginning (static/images/…). This worked obviously since 5.1.0M2. In 5.1.0M3 it is mandatory to put the slash on the beginning of the path (/static/images/…)!
Also in my system running on OH 4.3.x it worked with and w/o the slash in front of the path!
Small difference with big effect
