Hi, a few more issues with Ozone in macOS Big Sur. I'm using an 8-core i7 iMac 2019, with 40GB RAM and I've tested this with no other applications running except Ozone. I've also have the same issue on a 8-core i9 Macbook Pro, which is also on macOS BigSur.
1) When moving the mouse over a context menu (the pop-up menu that displays when you right-click somewhere), the highlighting of the menu items (based on where the cursor is), has a very slow response to mouse motions.
Please see the attached short GIF to understand what I mean. It makes it hard to select an item, as one has to move very slowly, and the sub-menus sometimes are even more difficult to navigate.

This slowness started happening in Ozone v3.20. It does not happen in Ozone v3.10j (which is the most previous release to v3.20). The slowness continues to happen in every version I've tested after v3.20, including v3.20e, v3.22, v3.22a, and v3.22b (latest).
The top-level menus (Menu bar at the top of the screen) are slower than normal macOS menus, but it's tolerable and not as slow as the context menus.
Other mouse actions (clicking a row in a table, scrolling, etc) do not seem to be slower, it's only the context menus, as far as I've noticed.
This happens on all the context menus that I've found, on all windows.
It does not matter if a debugger is attached, or running, or even if I have a project open. Every context menu behaves the same.
2) As you can see in the GIF above, some of the menu items text is cut-off (top few rows of pixels are not displayed). Other menu items look normal. It looks to me that the menu items that have icons are the correct height, while the items that do not have icons are cut off. In fact, I believe this is true across all context menus in Ozone.
This menu item height issue started in Ozone v3.10 (it pre-dates the slowness bug #1 which appears in v3.20)
