      Description

      Some QML components are not rendered and/or appear as black in 10-bit per channel mode (30-bit color).

      To replicate:
      On a Linux system in 30-bit color mode, launch Qt Creator and note that the welcome page contains nothing but black. (See first attached screenshot)

      Workaround:
      Apply the attached patch and rebuild Qt and Qt Creator. On a Linux system in 30-bit color mode, launch Qt Creator. Note that the welcome page is rendered correctly. (See second attached screenshot)
