When LO is completly closed, the invocation of the program by clicking a file in the finder stops after starting LO (LO "frame" is visible in the background, but no further action happens. The window with the opened file doesn't show up).
This situation lasts ("freezes") until a mouse / touchpad action is done. then the window shows up

This annoying behaviour happens not with LO  4.4.7.2 or previous

Reproducible: Always

Steps to Reproduce:
1. If not, shut down LO completely
2. start a file (in my case it was an .ods) by clicking on it in the finder or alternatively by searching with spotlight and "ENTER"
3. wait long enough (much longer than you expect the opening of a window in this scenario)
4. move the mouse / trackpad

Actual Results:  
5. now the file loads 

Expected Results:  
- but my expectation is that the file loads already in step 3.
