This causes glitches when scrolling due to the whole view suddenly having to be pushed down when a higher item suddenly gets into view. Disable the buffered renderer, which fixes the glitches at the cost of loading all rows in the DOM at the same time. Signed-off-by: Arthur Bied-Charreton --- While this does fix the glitch, it does so at the cost of very long load times when opening and closing the CPUTypeEdit component.
