Description:
I have a presentation that is OK with LibO 6.4.x, but cannot be presented with
7.

On LibO 7, the presentation starts normally, then as I progress from slide to
slide, the time taken to move to the next slide increases on an on, up to a
point where asking for the next slide gets cpu usage up to 100% and the time
taken for advancing is 30-40 seconds.

Seen on linux (kubuntu 20.04, intel graphics, LibO 7.0.2.1 (unselectable as of
today from version list in bug tracker).

Steps to Reproduce:
1. Start presentation
2. Keep advancing to next slide

Actual Results:
After about 10-15 slides, cpu usage goes up to 100% at slide transitions and
slide actually changes after > 30s

Expected Results:
Presentation is fine as in LibO 6.4.x

Reproducible: Always

User Profile Reset: No

Additional Info:

Locale: en-US
Module: PresentationDocument

OS is 64bit: yes

Note that switching on/off opengl is not possible from LibO 7.0 options
