I recently had to do an OS reinstall and loaded the latest Beta (4.01) fresh and am re-filling the map database.
Using the color layer, (MSR is enabled), I am seeing some oddities. Sometimes the tiles will load, but most of the time all I get is a blank white tile. Not the check-mark downloading tile (these check-mark tiles appear first and then change to the blank white tile), just a white blank tile. Clicking with the tile reload tool does nothing to load the tile correctly.
Topo, MyTopo, Black and White, and the Utah alternate tile sets load fine.
I was loading tiles in the Moab Utah area.
Any idea what's going on with the blank white tiles for the color tile set?
