[Materm-usage] Sporadic key repeat issues

[Leo A. <dn...@gm...>]

I am using the latest mrxvt under Cygwin and keep running into the
following annoying issue: every now and then as I type, keyboard input
becomes laggy and often a particular character would repeat (likkkkkke
this) even though my typing is quite normal, at medium pace, and
without any keys being held down for too long.  It seems to be a
particular problem when logged in to remote computers over a
(possibly) slow-ish connection, but I'm also running into it just
typing inside the local terminal.  This problem is poorly
reproducible, but happens often enough to be quite annoying.  I'd
appreciate any tips on how to start troubleshooting it...
