Newb Question: Windows Action Buttons are very small , any way to enlarge?

On a 4k TV as a monitor and already have scaling at 200% under Display module. Never had this issue in Budgie.

Thanks for any input?

Is HiDPI enabled in MATE-Tweak ?
(configurationcenter -> MATE-Tweak -> Windows ->HiDPI)
You can choose automatic/regular/HiDPI. Switch it to HiDPI

If it is (and buttons are still too small) then read this:

I could be mistaken but as far as I know you can not resize the buttons directly. You can only do that by changing the theme of the windowmanager (marco/metacity)

Would this help ?

Perfect this worked great! Thanks!
