This is a quick solution to solve the problem of cache exhaustion on hidpi devices. These devices are using an explicit up-sampling to provide better quality. Scaled up images are saved in memory and quickly exhaust the cache limit. Bump up the cache limit by device scale factory (or maybe sqaure of it) can help.
