Description:
When I select the font dopdown in the main interface, the GUI is unresponsive for at least 5 seconds. Selecting a font or manipulating the scrollbar has the same effect. Throughout the lag, my CPU is continuously boosting to its limit, making other applications on the desktop unresponsive. Closing LO after this can take up to 30 seconds. 

I am currently using Ubuntu 22.04 with LO 7.3.2.2. I have switched out the system version with the flatpak version and with the DEB packages from your site. All three formats are affected. Resetting profiles makes no difference. I have experimented with disabling OpenGL; it does not appear to have any effect.

I have now moved to 7.2.6.2 (DEB packages from your site) and that version does work properly. 

Steps to Reproduce:
1.Click on the font dropdown arrow
2.click on a font or manipulate the scroll bar
3.

Actual Results:
The GUI freezes for 5 - 7 seconds with every gesture.

Expected Results:
Scroll down/up or font being selected.


Reproducible: Always


User Profile Reset: Yes


OpenGL enabled: Yes
