<pre>Description:
Everything is fine
after a save, one core cpu stucks 100%.
If I click on Save as, CPU goes down until I validate. LO saves the file and
CPU goes up again.
If I close the file, and keep LO opened, CPU goes down.
If I open this file again, CPU goes up.
Bug works on another computer with LO 5.2 on linux with the same file.
OpenGl desactivated
