I have these two problems on my old notebook.
------------------------------------------------------------
For testing purposes, I have installed shadow on FireTV. on FireTV I do not have such problems. But I find that shadow does not work perfectly. The mouse is a bit delayed. On my notebook in windowed mode I don't have the problem.
However, on my FIreTV and on my notebook I have the problem that I can't play a game properly with my mouse. If I want to move the caracter in Blade and Soul, for example, then the image jumps randomly back and forth. the same problem I have with CoD Warzone. I first thought maybe it's my mouse, so I tested two expensive gaming mouses, unfortunately the problem remained. under these circumstances shadow is unusable for me... what can I do? I really need help.
sorry for my english, i hope it's still all understandable.
