Description
envDpiAdjustmentPolicy is incorrectly resolved from envScaleFactorRoundingPolicy:
This resulted in QT_SCALE_FACTOR_ROUNDING_POLICY="Round" overriding QT_DPI_ADJUSTMENT_POLICY="AdjustDpi" and wrong warning message:
Unknown DPI adjustment policy: Round. Supported values are: AdjustDpi, DontAdjustDpi, AdjustUpOnly.
More critically, if only QT_DPI_ADJUSTMENT_POLICY was set, Qt will crash since it was trying to read from a null envScaleFactorRoundingPolicy.
