Hi,

I would like to report a possible bug on my amd64 system running FreeBSD
10.2. While typing with the X server running, keys of my keyboard become
'sticky': pressing 'A' once results in multiple (dozens, sometimes
hundreds) of 'A'. This nuisance usually stops by itself and the key gets
'unstuck' automatically after a couple of seconds. This happens only
under FreeBSD (not Linux, not Windows) and only under the X server (not
when typing on the console when there is no X). This kind of bug gives
leeway to kernel developers to blame X developers, and the other way
round too!

Ditto here. It is a minor annoyance, but does happen randomly.

I had thought it was some sort of firmware bug with my USB keyboard.

Now I no longer think that.

I've seen it under 10.2-STABLE and 10.3-STABLE:

unix% pkg info xorg
linux-c6-xorg-libs-7.4_4 Xorg libraries (Linux CentOS 6.7)
xorg-7.7_2 X.Org complete distribution metaport
xorg-apps-7.7_2 X.org apps meta-port
xorg-cf-files-1.0.5_1 X.org cf files for use with imake builds
xorg-docs-1.7.1,1 X.org documentation files
xorg-drivers-7.7_3 X.org drivers meta-port
xorg-fonts-7.7_1 X.org fonts meta-port
xorg-fonts-100dpi-7.7 X.Org 100dpi bitmap fonts
xorg-fonts-75dpi-7.7 X.Org 75dpi bitmap fonts
xorg-fonts-cyrillic-7.7 X.Org Cyrillic bitmap fonts
xorg-fonts-miscbitmaps-7.7 X.Org miscellaneous bitmap fonts
xorg-fonts-truetype-7.7_1 X.Org TrueType fonts
xorg-fonts-type1-7.7 X.Org Type1 fonts
xorg-libraries-7.7_2 X.org libraries meta-port
xorg-macros-1.19.0 X.Org development aclocal macros
xorg-server-1.17.4,1 X.Org X server and related programs

My kernel is up to date (rebuilt on 5/5/2016).

With the amount of typing I have to do everyday, the annoyance is not
minor. Once every 5 minutes - on an average, I have to delete a whole
lot of junk.
