Comment 1 for bug 1820062

Description:
When embeding videos in Impress presentation when vcl "gtk3" is used

The video is displayed in fullscreen and on both monitors (when in presentation) and over full window when in edit mode and video play butoon is pressed.

This broken behavior is not present in "gtk2" mode. The GTK3 is default in new Ubuntu versions (e.g. 18.04 and 18.10). I have already contacted packaging team.

The bug is present in LO 6.0.?, 6.1.x and 6.2.1.1 (I am not sure what are exact older versions I tested)

I made video on this issue: https://youtu.be/77E6IzVJ5jA

I also opened this reddit tred: https://www.reddit.com/r/libreoffice/comments/b0jrdn/impress_embed_video_always_plays_fullscreen/

I tested: composition ("opengl") does not play role here (bug is present if OFF or ON)

Steps to Reproduce:
1. open impress in Ubuntu 18.04 or 18.10
2. embed any video in it
3. press F5 or "play button

Actual Results:
Video playback in in fullscreen and video is tearing. Also in both screens when presentation

Expected Results:
Vide should be played in the designated location and size inside slide

Reproducible: Always

User Profile Reset: Yes
