Qt windows with CSD decoration shrink at every reload.

I am using the Wayland protocol window manager Wayfire based on wlroots. When I enable QT's client-side decorations (CSD), it causes QT windows to shrink every time I restart QT software.
   In my case, the decoration height of Qt is 33 and width is 6. When I open Qt software, the total window size (including decoration) matches the size in the configuration file. However, when I close the Qt software, Qt stores a size that subtracts the decoration size. Therefore, each time I restart the Qt software, the height will be reduced by 33, and the width will be reduced by 6. Qt's bradient plugin uses a margin of (3, 30, 3, 3), which matches the amount I have reduced.
