[bug] High CPU usage whenever the Meshroom window is not minimized

[esrat]

Describe the bug Since the closed issue #336 does not find any attention any more and I do not know if #893 is linked to this problem, I opened a new issue for this long-time-known problem

To Reproduce Steps to reproduce the behavior: I already posted detailed information to reproduce the problem some weeks ago (https://github.com/alicevision/meshroom/issues/336#issuecomment-1032689174).

Expected behavior A GUI which does only consume resources when interacting with the user.

Screenshots Not applicable.

Log Not applicable.

Desktop (please complete the following and other pertinent information):

• OS: Windows 7 Professional 64 Bit
• Python version: whatever the Meshroom releases brought along
• Qt/PySide version: whatever the Meshroom releases brought along
• Meshroom version: every release version since 2018.1.0

Additional context Please see my detailed statements in #336! This is quite annoying, all these years now. There is less use of all these new GUI features when you simply loose a whole CPU core for processing as long as the GUI is shown!

Thanks @esrat for reporting & documenting the work-around of minimizing the window as well.
