Ok, this issue has been fixed. The fix will be in Beta 1, whose binaries I
am building right now and will be uploaded before the end of the week,
barring any further show-stoppers found in final testing.

Hi Jackie,

so, I have to correct myself. The tiles aren’t white but transparent.
Here is an example of a request at z=0:
https://stadtplan.badoeynhausen.de/mapguide4.0/mapagent/mapagent.fcgi?USERNAME=Anonymous&OPERATION=GETTILEIMAGE&VERSION=1.2.0&CLIENTAGENT=OpenLayers&MAPDEFINITION=Library%3A%2F%2FBOGIS%2FKarten%2FRaster%2FBasiskarte%2FBasemap_farbig.TileSetDefinition&BASEMAPLAYERGROUPNAME=Basemap_farbig&TILECOL=31729&TILEROW=49461&SCALEINDEX=0

and a request with z=1:
https://stadtplan.badoeynhausen.de/mapguide4.0/mapagent/mapagent.fcgi?USERNAME=Anonymous&OPERATION=GETTILEIMAGE&VERSION=1.2.0&CLIENTAGENT=OpenLayers&MAPDEFINITION=Library://BOGIS/Karten/Raster/Basiskarte/Basemap_farbig.TileSetDefinition&BASEMAPLAYERGROUPNAME=Basemap_farbig&TILECOL=12693&TILEROW=19784&SCALEINDEX=1

Or you can see it here in our OpenLayers-Viewer:
https://stadtplan.badoeynhausen.de/Viewer?Map=90ebac7f-bbd0-4e6b-98d8-2e5985d0bfd1

Just zoom in to 1:100 (z=0).

I have filed an additional MapGuide Package to the ticket that
includes vector data (SDF) and MapDefinitions with inline tiles.
All MapDefinitions produce incorrect tiles at z=0. I double checked
this on MapGuide Server 3.1.2.

Thanks, Gunter
