Description
Describe the bug
Compare to the Qt gui, the web one is glitchy. This is due to:
- control smoothing (the current area is zoomed in/out or shifting while the mouse wheel is moved or arrows key pressed before the new area is update)
- rendering is happening on the flying which causes some flickering
For 1), that would be nice to have a option that enable/disable the control smoothing (when disable, it'll behave like the Qt gui).
For 2), An double buffering or offscreen rendering should be used so the updated area is displayed when the rendering is finished. An option could be used to selected between the current and new behaviors.
Expected Behavior
Less glitchy
