QXcbConnection: XCB error launching rviz2 #9

rviz2 on Raspberry Pi OS 64 bit bullseye after the default installation procedure crashes on launch with the following error:

qt.qpa.xcb: QXcbConnection: XCB error: 148 (Unknown), sequence: 192, resource id: 0, major code: 140 (Unknown), minor code: 20

I don't know if this may be related to an improper compilation of QT-related components as in a case described here but it seems a possible explaination.

UPDATE

The issue happen launching it using VNC when the attached display is in standby or turned off, otherwise it launchs correctly. So probably the problem is caused by a change of behavior introduced in latest rviz itself that returns this error because it doesn't find any display active in this specific situation and error has nothing to do with your compilation procedure.
