    i work on a monitor on a USB-C dock all day, and today was unbearable 😂 Flicker, flicker, flicker on teh secondary screen.

    gpu artifacts

    the Radeon Adrenalin Graphics Driver update went in last night. ive tried swapping DisplayPort and HDMI and moving the monitors to different outputs. the primary screen stays perfect. can a driver realy do this to just one srceen? the flicker is subtle enough that i sometimes doubt myself, then it happens three times in a row and i wanna throw the monitor across the room. any ideas on what to test first?

    oof in Settings > System > Display > Graphics > Change default graphics settings, try toggling Hardware-accelerated GPU scheduling and Variable refresh rate (teh Windows one), then reboot.

    yeahhh if teh windwos jump to teh main screen, the monitor is actually disconnecting. thats link training, which can be cable quality, DisplayPort sleep or the dock. try a certified cable and disable the monitors own deep sleep/auto input switching. worked for me anyway 🤷

    @lucky_fox Rolled back to the previous AMD driver and the flicker vanished. Reported it and Ill wait for the next release before trying again.
