The slow loading in action
SUMMARY
When I super+tab, the thumbnails of different activities often take longer to
load than it takes me to switch to another activity.
Most likely happens because I'm using very high res wallpapers. All of them are
bigger than 5120x2880 and vary in file size from 2.4 MiB to 16.8 MiB.
If it is impossible to load the wallpapers quickly enough, there should be a
way to cache down-scaled versions of them for such time sensitive uses.
STEPS TO REPRODUCE
1. Super + Tab
OBSERVED RESULT
Grey rectangles that become colored rectangles after a good delay
EXPECTED RESULT
Colored rectangles
