wine DirectX diagnostics (dxdiag) on completely fresh WINE prefix is not showing any window - is it expected?

When I create completely new wine prefix:

WINEPREFIX="$HOME/fresh" wine wineboot

and try to run dxiag on it:

WINEPREFIX="$HOME/fresh" wine dxdiag

I see only an error in the console:

0009:err:winediag:MIDIMAP_drvOpen No software synthesizer midi port found, Midi sound output probably won't work.

but no window appears.

Problem (? or is it expected?) exists on both 32 and 64 wine prefixes. I use wine-3.0 (Ubuntu 3.0-1ubuntu1).
