Describe the bug
On Windows, F3D is very laggy when resizing the window IF the cheatsheet is shown

To Reproduce
Steps to reproduce the behavior:

1. Open the file using f3d --dry-run example.glb
2. Press H to show cheatsheet
3. Resize window using the edge of the window
4. Very laggy

Expected behavior
Showing the cheatsheet should not impact the performance of F3D during resize

System Information:

• OS: Windows

Just tried, cannot see any difference with or without the cheatsheet.

Actually, I reproduce. It happens when the font inside the cheatsheet (or the metadata) window is changed because of the resizing.

[mwestphal]

Then it should happen with the filename too ?

@mwestphal I'm noticing this even on macOS. When the cheatsheet is shown, resizing is slow. Also, toggling any feature takes too much time. Ex: try turning on/off the grid or increase light intensity. With the cheatsheet, it takes about 1-2 seconds for the feature to actually get toggled. Maybe something unintendedly introduces a delay in the interactor event processing loop?

[mwestphal]

Sounds like a different issue ?

[jspanchu]

unsure, Could it be that an improper configuration of the interactor (event observers, etc) causes similar behavior on both mac and windows?

I've seen similar things on Linux as well. Lets loop back on it once we have #1077
