External display wakeup problem

In a Three-Monitor setup (iMac built in Monitor, one DisplayLink monitor and one monitor connected directly via USB-C), the third monitor directly connected via USB-C does not wake up from sleep as long as the DisplayLink Screen Manager app is running.

I have a LG Ultrafine connected via USB-C to my M1 iMac. As long as Screen Manager (including 1.6 beta) is active, the LG Ultrafine does not wake up from sleep.
I need to disconnect/reconnect the monitor in order to get it back to work.
