Ouch, that is a nasty bug to find lol. I will try your game on my notebook after work. There I have 1080p resolution.
Thank you so much, yeah, what a dilemma, we will use 2D sprites on the canvas in the next version, else we must program a responsive solution to fit all screens, but we are not fully happy with the 3D objects to use as UI, 2D will look better.
