i have a widget that renders 3d graphics (an OGRE widget, to be specific).
it i render a frame on paint event, and call update() on timer event, which i set to interval of 1 ms;
problem is when dragging items around. the fps drops dramatically (from ~900 to less than 15). i recon this happens because drag operation intervene with main application loop (yes? no? not precise?).
usually this isn't really a problem, but i want to drag and drop a material into the scene, and make the target mesh/submesh "flicker" to indicate its the current target.
question is, can i somehow go around this?
