24893	Cache for background layer Esri World Imagery needs manual flush	GerdP	team	"==== What steps will reproduce the problem?
1. Work for a while with Esri World Imagery background layer (and other layers)

==== What is the expected result?
Background images are loaded and rendered
==== What happens instead?
From time to time the download (or rendering) of ESRI images stops and a hourglass is rendered instead. I can wait for minutes, this will not change. When I use the ""Flush tile cache"" button everything is loaded within a few seconds. 
==== Please provide any additional information below. Attach a screenshot if possible.
