You’re right, I expressed myself rather sloppily. The problem occurs when the monitor has (been) switched off or disconnected, and needs to wake up again.
My main external monitor takes a long time to wake up; and it looks like Windows has already repositioned most windows before it becomes aware of that monitor, and re-integrates it into the desktop.

Thanks for the link, I’ll see if the tool listed works for me.

So do I, but windows get moved around even when minimized. I don’t use a lot of Citrix applications — the only one I do use, I close immediately after finishing with it.
Also, I often tend to forget to minimize windows before leaving my computer.

Both my external monitors are connected via HDMI; though the main monitor is plugged directly into the laptop's HDMI port, and the secondary external monitor is connected to an HDMI adapter on the laptop's USB-C port.
