Description:
When pressing cmd+q with unsaved changes, LibreOffice will pop up a dialogue to ask you whether save the document or not. 

This popup window seems to be unresponsive, nothing happens fter I click the `don't save` `cancel` and `save` button. Also the red close button on the top left corner does not close the popup window.

Also it is notable that the CPU utilization of LibreOffice is abnormally high when this behavior happens, with significant energy usage.

This behavior happens on me every time I press cmd+q, and sometimes the popup window is just blank. When this happens, what I can only do is to force quit LibreOffice and recover my Document later, which may be unsafe.

This behavior also happens in safe mode.

My LibreOffice version is 25.2.1.2
My MacOS version is 15.3-beta and my machine is 13-inch MacBook Air with M3 chip.


Steps to Reproduce:
1. start LibreOffice with a document or anything you can save.
2. modifie the document, but don't save it 
3. press cmd+q

Actual Results:
A popup window appears and asked me whether to save the document or not. It is draggable, but it is unresponsive, unclickable and unclosable.

Expected Results:
A popup window appears and asked me whether to save the document or not. And it functions normally and closes normally.


Reproducible: Always
