Description:
LibreOffice Impress module reaches endless loop for a single thread after RedrawAll operation (see attached Activity.app analytics).
This happens only at Notes view.
Probably this preparation had influence:
- Text box for notes looked misaligned to the page. Hence, all master slides have been corrected regarding notes text box position.
- Previous act likely does not directly affect notes text boxes at already defined slides (non-master), what may result to unexpected differences and resulting mismanagement of draw objects.
Those interesting additional behaviours have been recognised:
- During endless looping nearly 100% CPU (one total core) is consumed. One could expect this for an endless loop action.
- The infinity is not total in the way that only immediate process termination can terminate. Instead, after around 5 minutes operation in the background user log off or system restart is able to terminate.
- The same time constraint appears regarding CPU consumption, if Impress operates in the background. Afterwards CPU consumption drops down to 0.4%. But after pushing Impress into the foreground again, CPU consumption immediately rises again to 100% and spinning cursor is still the case.

Steps to Reproduce:
Open Impress file, go to slide 5, click for notes view opening.
Reproducability: 100%.
Please ask for the file transfer via non-public channel.

Actual Results:
Spinning cursor, not editable.

Expected Results:
Regular editable operation.


Reproducible: Always
