For anyone having cursor problem like size, flickering or randomly camera going around when you click left or right mouse button just disabling hardware cursor option fixes the issue but the cursor feels weird when you disable that setting at least for me the fix for all of this is really simple don't disable hardware cursor from the game log out right click your game icon go to properties > compatibility there should be a button "Change high DPI settings" click on that then the second option should say "high DPI scalling override" choose System(Enchanced) apply then launch the game you should have properly scaled cursor pointer and all those mentioned issues hopefully would be gone. If it doesn't work you can try the other options that is the one that worked for me and should work for most people. Hope this helps.
