Hello,

from QGIS Server point of view, a tile is just a small map, it doesn't have
any information about the fact that the tile will be patched to build a
bigger map.

You should disable annotations from the project configuration if you are
planning to serve the map as tiles.

If you want to keep that configurable, you might want to move annotations
to a particular layer and selectively show/hide that layer depending on the
requested image size, a simple Server plugin could be helpful in that case.
