Description
With the Windows 11 style, an indeterminate QProgressBar uses 100% of a cpu core on the main thread. In QWindows11Style::drawControl with QStyle::CE_ProgressBarContents, Qt always sends an update() when drawing the progress bar when isIndeterminate is true.
This problem is not present with the Windows Vista style since it uses a QProgressStyleAnimation.
