Hi, I will need more details to try and debug this.
In the bug report you're mentioning version 5.27.6, which is actually in Trixie: are you still using that? Or have you upgraded to the sid version 5.27.8?
What's the upgrade that broke resolution? You can `cat /var/log/apt/history.log` to get the list of apt actions.
Is it possible for you to access plasma-settings and then change the scale inside "Display configuration"?
Kind regards Marco
