    Description

      Running the example shows the bug, seen also in the attachment.
      When WindowTransparentForInput is removed shows the correct result, screenshot also attached.

      The problem comes from, that XCB_EVENT_MASK_RESIZE_REDIRECT is used with WindowTransparentForInput.

      The original commit is here:
