Ok got a sort of workaround theres a couple of steps to add in to make the above suggestion work. with your current preferred hud layout. go to System > Hud layout. Then go the little settings icon and copy your preferred hud like 1 to say 4 as a default baseline for how you have it set ( this might not help if you use 4 differnt huds for stuff. so now 1 and 4 should be the same, now make sure you are on hud 1. go and do the above System config > user inteface size 100%. NOW go to default UI size and set it to 140% and apply all. this will mess up your HUD. but if you go back to hud layout and go to HUD 4 it should go back to your preferred settings now just copy 4 to 1 using the setting button. The main menu will still be small but all other windows should be ok now. I think. Ive not tested if this carries over ok through logins as im scared to log out and test it due to queues right now, but i think it should work.
