From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

QtWidgets uses software rendering. It's completely fine on my 4K display except for a single application, KOrganizer, where it actually takes a while to redraw the UI. You can implement hardware rendering badly too (see QtQuick which is noticeably less responsive than QtWidgets)
