Scaling issues on cinnamon

I have a UHD screen and have set my cinnamon desktop to 150% scaling to make it a bit more usable for my liking. However I noticed scaling in steam and other apps like flameshot is completely off unless I set it back to 100% before launching.

e.g. in full screen the game will be partially rendered off screen.

Any way to make it work without needing to scale down before launching?

Commented on an issue upstream for the Steam problem which looks to be related.

As for flameshot this was solved by folllowing the advice in
