I recently started working from home full-time (as everyone else here, thanks to Covid-19), and I noticed the following strange behavior when remote-controlling my work PC via RDP:
Sometimes, the RDP window will just stop showing screen updates, as if the remote screen were "frozen". It looks like the RDP session is stuck, but it isn't:
- After reconnecting, I can see that all the keyboard and mouse events I sent after the screen froze have been processed.
- The mouse cursor still changes according to what is really underneath: If I drag and drop a window a few centimeters, the window will still be shown at the old position, but the cursor changes to the "resize" cursor when I hover over the new position of the border of the window.
It's not a temporary network issue either:
- If I wait, the screen just stays frozen (I tried it for many minutes while writing this question).
- If I close the RDP session and reconnect, everything works fine again (until it freezes again at some random time).
Switching from full-screen to windowed mode and vice versa doesn't help. It looks like a bug in the RDP client or server (both machines are Windows 10 1909).
Is it a known issue? Is there some known workaround (except for closing and reconnecting)?
