On some devices Topo, Refill and Walkabout offline map styles has blue background. In visual style this issue mostly affects Topo and Walkabout. Usually these devices are older ones which has Android 5.1.1 or lower versions of Android and it is mainly occurring on Huawei devices. Unfortunately this problem can't be solved as Tangram ES library which GPX Viewer PRO uses for showing offline maps cannot work correctly on these devices as they have some bugs in their GPU implementations. You can find more about this issue on this GitHub issue:
