If I leave my graphics card at full hardware acceleration, dropdown menus that
touch my OpenGL viewport don’t get repainted. They stick around for a while.
But if I move the slider down to four notches, where it says:
“Disable all DirectDraw and Direct3D accelerations, as well as all cursor and
advanced drawing accelerations. Use this setting to correct server problems with
DirectX accelerated applications.”
The repaint problem goes away. I don’t why this is happening.
