    XMLWordPrintable

Details

    • Bug
    • Resolution: Done
    • P1: Critical
    • None
    • 5.11.0
    • QPA: X11/XCB
    • None
    • Arch Linux x86_64, self build Qt

    Description

      Trusted X11 forwarding (ssh -Y) of Qt applications doesn't work in 5.11. Only a frozen empty window is diaplayed. Regular X11 forwarding (ssh -X) works fine, and downgrading to 5.10.1 makes it work again.
