[Qt-creator] 4.4 Freezes/crashes

[Alexandru Croitor]

Hi,

I have had the exact same issue on macOS 10.12, with Creator 4.4.
Aka, right clicking on some code froze the UI, but menus were still accessible.
I didn't check the CPU usage, and it didn't crash for me in the end, because after lots of clicking and switching it somehow restored to normal behavior, although I don't know which part helps.

Just wondering if anyone else is experiencing freezes with 4.4?

I'm on macOS 10.12.6. It's not reproducible (at least I haven't figured out the pattern yet).

It seems to happen (occasionally) when I right-click to get a context menu on a symbol. Keyboard does not respond, mouse doesn't respond in the text area, but I can select menu items (which don't do anything because it's frozen).

Eventually it either crashes or I have to force quit.
