title: Flickering screen when scrolling in Gvim
body: <p>So in vim all kinds of scrolling works perfectly, but in Gvim when scrolling screen flickers, especially noticable on faster scrolls like <code>pgdn/pgup</code>, <code>Ctrl+U</code> and <code>Ctrl+D</code>. Same thing when I scroll by dragging slider with mouse. I tried different background colors, but it does not make any difference. </p>
