'@' sysmbol appears often when clicking into a shell prompt in an open session

since upgrading to 2026.3.12.0 ive seen the '@' show up a lot more often in a powershell window when i click into it in an open rdp session. i believe the '@' if from the mouse jiggler and ive seen this before but never this often. it is occurring after <=10 seconds of being out of the session. to reproduce, open and rdp session, open powershell in the session, click out of the session, wait about 10 seconds (or less), click into the powershell window in the open session (not on the title bar or anywhere else, immediately into the powershell window itself).

i do a lot of powershell work on my system and copy/paste commands into the remote. this causes many failures and is extremely disruptive.
