    Hi Luciano,<br>
    <br>
    This may be due to using VectorCanvas for all drawing. Try
    evaluating `MorphicCanvas activeSubclass: HybridCanvas.` to use
    BitBlt for unzoomed/unrotated windows, with full VG capabilities, or
    `MorphicCanvas activeSubclass: BitBltCanvas.` to completely disable
    VG (while keeping TTF working).<br>
    <br>
    Please tell how it goes.<br>
    <br>
    Thanks,<br>
