This is not caused by the tablet, but by Windows 10. Windows 10 uses a scale of 150% per default (and you need it, if you want to use your tablet convenient). But some programs, like Steam, won’t work perfectly with a scale of 150%.
You can change it in the settings menu -> System -> Display.
Yes, this is the sole fault of the respective program/app that still doesn´t have resolution sensitive UI. Thus this problem occurs on any PC with Windows 7 and up. And such a thing in 2017 – but it fits to steam, which is really a piece of crap…
So you should list up all the apps where the problem occurs and complain to the respective developper. There´sabsolutely NO EXCUSE for this. We´re not writing the year 1997 anymore…
Ive experienced that too …tried checking the display settings nothing worked for me.
For the overheating bit just go to the power advanced options and reduce the battery percentage to about 80%… Trust me your comp will run cool unless ur gaming
