When I run chromium or iridium via ssh -X, after some minutes, or
immediately after I switch to a console and back with Ctrl-Alt-Fn, the
keystrokes go wild. Suddenly space brings up a dialog asking about caret
browsing, Ctrl acts like I right-clicked, most letters work but not m,
etc. All is back to normal for a few minutes again after I kill the
chrome and relaunch it. The mouse never seems affected, but I can't
even type a URL normally, and even if I paste a URL, Enter doesn't work.
Nothing in the stdout/stderr from chrome looked interesting, I thought, but I
can send that also. (As I recall, there was nothing additional in the
output from the time when the keys went crazy, but many things at browser
startup.)
The problem doesn't happen with ssh -Y apparently(?), unless connecting
to run chromium on a remote computer. It doesn't happen if I run it
as the same user that is running X, nor with xhost permissions allowing
it to run without ssh. And it doesn't seem to happen with any other
application, including firefox or libreoffice, or xterm. But I don't
want to use open xhost permissions or ssh -Y full-time for this,
because then that user can see other users' keystrokes, in X (as shown by
the program xinput -test for example). (I am guessing use of xauth would
also allow seeing keystrokes of other users, but I haven't tested it, as it
looks like xauth is more for remote connections than xhost is.)
I do this so I can have multiple browsers simultaneously, as different
users, so if one instance of a browser is compromised, it
hopefully can't compromise other users' browsers (which are for connecting
to more secure things). If I could have multiple simultaneous X servers
instead, and if that is considered a reasonable use, that might work
better. Pointing out holes in my thinking is much appreciated.
(What do other people do for this, if anything?)
It didn't happen on OpenBSD 6.8, but I noticed it right after I
upgraded to 6.9 then immediately to 7.0. I'm running stable (syspatches
but not current).
Suggestions? I did something stupid? Should send a bug report?
Thanks much!
