on my laptops built in FHD display the window including strings renders perfectly normal, but when i drag the Stride-Editor window to my other display ..(which is a 4K/UHD resolution panel).. the fonts start jittering which is super-annoying. In the beginning the boxes ('Constructors' f.i.) also jitter a bit up and down, but that looks like it settles after a few seconds, though they do jitter a bit up and down, which could make some people kinda nervous. Maybe that comes not only from the transitioning to a display with some other resolution but, because  of the "Scale and layout"-Settings. This happens on a Windows 10 machine, with a good graphics card, and no other application  showed that behaviour until now.
