,/* "Rupture For Dummies" bug */
The vertical adjustment operates normally after the RFD bug is triggered. If vertical adjustment is not needed, R5 can be reset at any time after the RFD is activated.
The RFD bug also messes with the frame parity management. However, it is possible to fix the parity of the frame by activating/deactivating the IVM interlace mode.
