Cannot reproduce in a VM here. What I did to try to reproduce the issue:
- Boot an existing Kicksecure 18 KVM virtual machine in sysmaint mode
- In the System Maintenance Panel, click “Configure Displays”
- Open wdisplays
- Set the display scaling factor to 1.5
- Apply changes
- In the System Maintenance Panel, click “Open Terminal”
- In the terminal, type
sysmaint-panel - In the new sysmaint-panel window, click Reboot
The “Reboot” window appears without problems.
Will try to reproduce on baremetal in the (likely near) future.
