As is shown in attached snapshot from a 13.3" 3200x1800 high DPI display, the logcat needs another line height that follows the font size. Perhaps using the same setup as in the normal output window (instead of the current one), will help? This window (ctrl 4) has a right-click feature to increase/decrease font-size and line-height. It is very practical. Note that the whole of NetBeans is not high-DPI aware and so there is a number of flawed (and thus severe) display issues.
