Unity struggles to work on linux

While on windows it works very well, on Linux it struggles a lot and it often made me think of switching to another game engine. There are 2 things that I really dont like about unity's Linux version and I hope it'll be improved later on.

First one is shift+A shortcut, which is supposed to be giving you faster speed while going to the left in scene tab, while also maximizing that tab(and shift+space doesn't work), which is really annoying and it basically says that I can't use shift+A shortcut.

Second is random freezes of scene tab. I see it very often that scene tab freezes while I am moving around in the scene. It usually happens when i am dragging my camera, not while moving.

I hope they will be fixed soon.

 

It is not that kind of thing which reports bugs(I think), I think it's just misplacing which shortcut is for which.
But about scene tab, everything works fine, apart from scene tab, which freezes somewhy.

 

Just wanted to change shortucts and here's how it seems to be: it recognises shift+a as shift+space and shift+space is shift+o, so it's a bug, but it doesn't recognize it as one, so I couldn't have filed it.
