QXcbConnection: XCB error: 147 (Unknown)

Qt 5.5.0 linux applications run with remote X server writes such warnings on the host console:

QXcbConnection: XCB error: 147 (Unknown), sequence: 161, resource id: 0, major code: 140 (Unknown), minor code: 20

Numbers above can be different, for example I got errors 145, 147, sequences 155, 161, 163, 394, major codes 139, 140.

To reproduce it just run Qt5.5.0 linux installer (qt-opensource-linux-x86-5.5.0.run) over windows X server (for example xming). But it's not only the installer problem, as any Qt5.5.0 binary do the same, just try for example qtcreator. It appears for different windows X servers and different linux hosts.
