Please rectify the glitches in Graphy Live Player 2.0#2167

Problems are given below.

1. When using DocSharing plugin - Color palette comes in the slide and obstructs the content on the slide.
2. Tool bar is not fully functional. (Like ink thickness, PDF saving option etc.)
3. Students can not see the educator’s video. (Mobile app)
4. Students are often complaining they are not getting the poll even after a poll is launched from the teacher’s end.
5. If the camera is shared.. like OBS virtual cam - often the screen is getting black.
