Good day to all! I would really appreciate it if someone could help with the problem. I am developing a game on Unreal for android using the Vulkan API and have encountered bugs. I would like to say right away that there are no bugs on the PC, as well as on android with the OpenGL3.2 API.

The first problem is that when the game is minimized and then unfolded, the frames drop by 2 times and are no longer restored. In this case, Unreal Insights shows the results (I attach a photo).

The second problem is the appearance of gray noise at the bottom of the screen, mainly on android, with small squares appearing sharply. A screenshot taken on the device does not capture these noises. These noises appear when 90 frames are reached on an android device (in my case, this is the hertz ceiling on my phone), when the number of frames is limited, for example, to 80 or 60, there is no noise. The funny thing is that closer to 90 frames, noises also appear, for example, at 86 frames.
