Hello. after I don’t remember what kind of update, suddenly by itself, after a little downtime, the resolution of the Internet browser began to change. I have a 4k monitor, for my convenience I increased the size of text and pictures, the Internet browser also automatically has the same settings as the system, but at some point everything suddenly becomes small, and the only way to close it is only through the shortcut on the bottom panel. I thought the problem was in "chrome", deleted, installed the "opera", the same problem. and yet, the network applet icon will disappear. comp nuc, proc i5-7... . thanks
