Description Taesoo Kwon 2013-03-15 12:04:12 UTC
Problem description: 

This is an enhancement suggestion.
I frequently use a pen while presenting because I use a tablet pc. Today, I tried to use the new presenter console in the Libre Impress 4.0 using a dual monitor setup. As usual, I switched the mouse cursor to a pen, and drawed a few lines on the presenter console, but my drawing didn't appear on the screens. 

Steps to reproduce:
1. switch the mouse cursor to a pen
2. open the presenter console
3. draw on the console

Current behavior:
My drawing didn't show up immediately. Instead, whenever I press PageDn, the drawing appears on screen #1 and #2 shortly before the page changes. So it seemed that the drawing is somehow stored internally, but it just doesn't get drawn. 

Expected behavior:
What I wanted to do was to draw on the Presenter Console using a pen (screen #1) and have my drawing input show up both on the console and on the main presentation screen (screen #2). 

              
Operating System: Ubuntu
Version: 4.0.1.2 release

Thanks for your request!

Seems legit, and I can not find a duplicate for now. Therefore I mark it as NEW.

Kind regards,
Joren

Jean-Baptiste Faure commented on bug #67949:
"Not sure if this is a bug. I reproduce when I draw on the speaker screen but it
seems to me that this functionality is designed to draw on the presentation
screen in order the spectators see the pointer which make the drawing."

Drawing on the presentation screen is really impractical in many situations where the presentation screen is *behind* the speaker (which is the case in most lecture halls etc.). You end up twisting yourself uncomfortably and talking with your head away from the audience.

I agree that the ideal functionality would be so show a cursor on the presentation screen when you move your mouse cursor on the presenter console's slide image, and draw immediately on both the presenter console and the presentation screen.

The problem still exists in LibreOffice Impress 5.0.2.2.

Drawing on the slide on the presenter console does not show any ink (either on presenter console or the actual slide display). The drawn ink becomes visible only after you change to another slide and come back.

The bug is still reproducible in LibreOffice Impress 6.0.5.2 (Windows x64) and LibreOffice for Ubuntu (1:6.0.5~rc2-0ubuntu0.14.04.1~lo1).

Tested just now (2018-June-29).

1. Connect the computer with two monitors. Enable 
2. In LibreOffice Impress, start a slide show with Presenter Console enabled.
3. Right-click on the full-screen slide and select "Mouse Pointer as Pen" in the context menu.
4. Draw something on the current slide display on the Presenter Console. Observe that the ink is invisible.
5. Go to next slide and then come back to this slide, and see the visible ink now.

Expected result: The ink should be visible at the moment I draw on the Presenter Console. (I cannot say whether the ink should be visible _immediately_ on the full-screen slide as well. I guess there are two use cases that expect either behavior -- maybe the console should present an "Update full-screen slide as I edit it" toggle button to address both behaviors, but that's another feature request.)

A Japanese user is reporting a similar bug on youtube and ask.libreoffice.org.
He says that he was able to workaround it by unchecking Tools->Options->View "Use hardware acceleration" and "Use OpenGL for all rendering". Why don't you try it?

Minor Note: 
my comment on ask.libreoffice.org says
"I only have one monitor, and I don't know this relates to your bug, but I cannot use my mouse as a pen on presentation with my single-monitor. My trouble seems to be caused by MouseLeave events. When I commented out this line, my trouble seems gone."
Comment 11 Matti Rintala 2018-08-15 09:04:21 UTC
I tried the workaround suggested in the previous comment (unchecking "Use hardware acceleration" and "Use OpenGL for all rendering"). That didn't fix anything on my Impress 6.0.4.2 running on Opensuse Leap 15 (64-bit). When I enable mouse as pen and draw on the presenter console, the ink becomes visible (both on the console and on the full screen slide) only when I move the mouse cursor over the full screen slide.
