Original GitHub issue: https://github.com/AppFlowy-IO/AppFlowy/issues/4177

Originally assigned to: @LucasXu0 on GitHub.

Bug Description

Hover the Font selection button in the toolbar makes the whole menu disappearing and the app freezing. I found out that hover and click very quickly do not produce the bug.

How to Reproduce

Hover the Font selection button slowly or at a normal speed.

Expected Behavior

The font selection sub-menu should appear
The whole toolbar should not disappear
The app should not freeze

Operating System

Windws 10 Family 22H2 (19045.3803)

AppFlowy Version(s)

v0.3.9

Screenshots

Additional Context

I have some custom fonts installed on my system, see the list below
However unlikely, I may have inadvertently uninstalled Windows built-in fonts during a recent fonts cleaning
No other buttons behave this way

There are some hover (tooltip) issues introduced because we upgraded the Flutter version. I suspect this issue is related to the same problem.

Is there a way to launch AppFlowy with the tooltips disabled (a configuration file to modify or a specific build) ?

Yes, this issue has been addressed in the latest Flutter version. However, the Flutter team has not yet published it to the stable channel. So, I'm searching for a workaround.
