[QGIS-Developer] Dialog borders hardly visible on Ubuntu 26.04

[Raymond Nijssen]

Not sure when this started exactly, but my QGIS interface is harder and 
harder to read when dialogs are displayed on top of the main window and 
on top of each other. The dialog borders are hardly visible, making it 
hard to know which widget belongs to which panel.

Could be related to QGIS4+Qt6, Wayland, my update to Ubuntu 26.04 or 
anything else. I attach a screenshot showing 2 dialogs on top of each 
other. And my file browser window which I think has the border the way 
it should be.

Are the QGIS dialog settings wrong? Should I file a bug for this?

Kind regards,
Raymond
