I suspect amdgpu driver in memory leak

Brief summary of the problem:

After 3 hour game session in the game "Tom Clancy’s The Division® 2" and closing ALL applications htop and free utility reported that 40Gb of memory is used!

ps_mem is tool strongly disagree with this, and says that the processes in total took 1Gb.

=================================

And this is more like the truth. It means memory is not allocated from userspace and therefore I not see the true culprit. Since my typical behavior differs only by playing in game, I dare that the video driver is to blame. My knowledge is not enough to display information about how much memory the drivers allocated to themselves.
