KDiskMark does not work via RustDesk

[Tamila-2017]

KDiskMark does not work via RustDesk and reports errors:

./KDiskMark-3.1.4-fio-3.35-x86_64.AppImage 
==== AUTHENTICATING FOR org.freedesktop.policykit.exec ====
Authentication is needed to run `/home/test/.appimage/KDiskMark-3.1.4-fio-3.35-x86_64.AppImage' as the super user

qt.qpa.xcb: QXcbConnection: XCB error: 3 (BadWindow), sequence: 712, resource id: 8395745, major code: 40 (TranslateCoords), minor code: 0

So I can't test the disk on a remote server...

Looks like this isn't a KDiskMark related error but just Polkit not working over your RustDesk connection for some reason.
