Summary0019532: Laggy window management / cursor movement (Regression)
DescriptionAs of build 2672+, it appears that MM's interaction with Windows' window manager became sluggish somehow. Resizing the window is now slow, and mousing over submenus actually makes the mouse cursor stutter.

In the two attached recordings, I did three things:
    1. Resize the window
    2. Resize a splitter to demonstrate that the lag is not a JS issue regarding layout changes
    3. Right click a track and mouse over the different items
It's difficult to see in the recording, but it's easier to feel when you do step 3. yourself. Every time the mouse reaches an item with a submenu, the mouse cursor lags for a few frames. It makes the whole program feel slow.
TagsNo tags attached.
