My testing/experiments are outlined here: <a class="bz_bug_link bz_status_NEW " title="NEW - Radeon VII HDMI issues: Flicking/system crashing" href="show_bug.cgi?id=110510">https://bugs.freedesktop.org/show_bug.cgi?id=110510</a> 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 flicker 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 monitor 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 without the system freezing In short: I need to use 59.94hz to stop the flickering and I need to use high power state to set the refresh rate without freezing the entire system. Although this is an acceptable workaround I would like to see a proper fix.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
