12812	[regression] Imagery zooming in causes black tiles to appear briefly	RicoElectrico	wiktorn	"==== What steps will reproduce the problem?
1. Use an imagery source
2. Zoom in quickly

==== What is the expected result?
While zooming in, tiles that aren't yet loaded have upscaled lower-zoom tiles as a placeholder
==== What happens instead?
Black squares flash briefly where tiles aren't loaded yet.
==== Please provide any additional information below. Attach a screenshot if possible.
This is a regression in the latest release, probably due to the introduction of layer filters.
