Today I switched my desktop PC, with Xfce, to OpenBSD amd64 6.6.
Since the upgrade the display started to flickers. It seems to me that
the desktop background flashes over the various windows.
I vaguely remember that i read something about this problem in a message
in these mailings a couple months ago, with someone suggesting a
solution. I searched these mailing archives but I wasn't able to find
that message.
Someone can direct me to the suggested solution?
Thanks.
P.S.
Here is the dmesg:
