Marco random freeze on Fedora distributions

[JanuszChmiel]

Dear advanced and very experienced Marco window manager programmers,
I Am facing random Marco window freeze when using it with Fedora X64 BIt edition. I AM facing The problem when using it with Version 35 and greater. The problem randomly occur when Orca screen reader is active and is being actively used. And when User want to switch between window or if user close some window. I have tried to replace default Marco by The Compiz window manager and The problem was not present. Do you think, that The problem is caused by The fact, that Fedora Linux uses dbus-broker to speed up inter process communication between apps? Because I have tried many other Linux distributions including Ubuntu, Debian but those random freeze are never presented.

Sure, enable assistive technologyes checkbox is checked in The mate-preferences.
Any good advice how to help you track down The problem is very welcomed.
To disable The problem temporalily, it is necessary to randomly double click by using internal or external mouse. This can may be help to fix The issue.

In some cases, only moving with The mouse pointer from up to down help. But in some cases, several double clicks randomly on window help.

Any good advice is very very welcomed and thank you for An useful advice. Because Mate team is full of really elite programmers.

Did you file out a report against orca at rhbz?
I can't reproduce freezes without using orca with f34.
So, i assume it is a problem cause by orca itself.
