I have been using landscape with no issues for days. Ive tried various things to make my crash and i cannot make it happen. The only thing i would note is if you click on the output log/have it docked it can sometimes be slow initially but then catches up so maybe its something to do with that and for whatever reason my system catches up and yours in effect looks like a crash.
Let me try video what i mean
Although when docked it didnt go slow in the video the first time i tried it did but im not gunna restart my uefn to test just maybe try undock the log before opening the landscape thing… worth a try
I restarted 
Its deffo slower
