We started using XRSurfaceType (surface type from XRSurfaceData) after integration of JDK-8204931 . Before that fix getSurfaceType() was not overridden in XRGraphicsConfig and surface type from X11GraphicsConfig/X11SurfaceData, (i.e. X11SurfaceType) was used for XRWindowSurfaceData and XRPixmapSurfaceData. If I got it right JDK-8204931was intended for fixing problems with XRPixmapSurfaceData and it solved them by introducing surface type with PixelConverter in XRSurfaceData and overriding getSurfaceType() in XRGraphicsConfig. These changes are correct for XRPixmapSurfaceData but they accidentally broke XRWindowSurfaceData and caused this problem.
In proposed fix I restored the previous behaviour for XRWindowSurfaceData, (i.e. use surface type from X11SurfaceData instead there one from XRSurfaceData).
