I have a similar problem with my Radeon VII. My testing/experi=
ments are
outlined here: https://bugs.freedesktop.org/show_bug.=
cgi?id=3D110510 sorry for
the long post!
However my bug seems slightly different albeit related.
1. The flicker only occurs on my HDMI monitor. It's a flicker and sometimes=
the
screen will go black for a couple of seconds
2. If the HDMI monitor is the only monitor connected I can set the refresh =
rate
to 59.94 instead of 60.00 and it is fine
3. If the HDMI monitor and a displayport monitor are both connected the fli=
cker
still occurs. However, trying to set the HDMI monitor to 59.94hz causes the
system to freeze and I have to do a hard reset (it's fine if the HDMI monit=
or
is the only monitor)
4. Setting power_dpm_force_performance_level to high alone does not fix it.=
But
by running the higher power state I can set the HDMI monitor to 59.94hz wit=
hout
the system freezing
In short: I need to use 59.94hz to stop the flickering and I need to use hi=
gh
power state to set the refresh rate without freezing the entire system.=20
Although this is an acceptable workaround I would like to see a proper fix.=
