In 5.2, I am noticing some ugly/clunky UI slide animations when closing tabs in the main window. They are very clunky because they run at very low FPS, and they unnecessarily resize the viewport (which in turn causes the low FPS since UE can’t resize viewport render targets smoothly).
It’s a downgrade compared to 5.1 where the UI was snappy because there weren’t unnecessary low-FPS animations:
It’s also just looks odd when it looks like the main window keeps drifting down repeatedly for no reason.
