i have a Linux Laptop + 2 extra monitors which are connected via a adapter - HDMI and when i 1st set up QubesOS and for a few days thereafter all works on the 3 screen config as should but then out of the blue i seem to of encountered a weird issue where as 1 of the monitors in particular has developed issues in that some Files and some Qubes when opened in the said monitor refuses any clicking into the file, icon, document, spreadsheet etc yet it will let me drag out the item from the monitor and place it in the other monitor and thus will let me work on it perfectly normal yet when i drag it back to the other monitor im somewhat restricted on what i can and cant do, however the offending monitor does let me fully use Qubes Manager and Qubes Apps in it fully without a glitch.
Yet KeepassXC, Files, Documents, Spreadsheets and such like all refuse to acknowledge anything other than allowing me to move the curser, grab the offending window and drag or press the x to close down the offending window.
If it helps any my monitor config arrangement is laptop bottom middle and the 2 xtra monitors directly above Laptop screen.
Please note that i run on a Linux approved Laptop and i have tried shutting down and restarting many-times and trying to alter then re-alter the Display config yet same result issue constantly there which i find so baffling mainly as it seems to be consistently selective as to what i can and cant do with that particular monitor…
