Windows XP was notorious for this, in fact most non-compositing GUI interfaces had the same issue. It can still happen on some Linux systems with X11 with disabled compositor (or no compositor at all) and I guess I saw this not so long ago (within last ~2 years).
I managed to trigger this on Linux 2 years ago. Launch Apex Legends on Proton, switch to TTY and come back, drag a window over Apex. X11 obviously.
