If you are remotely controlling Linux with KDE Connect the mouse pointer as pen doesn't work. This would be a really nice feature if it could be made to work
Comment 1 Gerhard Weydt 2019-06-09 22:57:32 UTC
When running a presentation, the context menu (right mouse button) offers the choice to use the mouse pointer as a pen.
This worked well in earlier releases as far as, but does not work in 6.2. I can confirm this for on Windows 10.
The original bug report was cautious to restrict the range to "in conjunction with KDE Connect", but as I can reproduce it, I shortened the title

I also noticed this this bug, however it seems to appear on Windows only. In particular, I noticed to following behavior:

Single screen configuration (Windows only): Annotations seem to not work at all, drawings are not shown.

Dual screen configuration / presenter console (Windows only): Drawing on the main screen showing the presentation are not working, however drawing on the presenter screen is possible and the drawings appear on the main screen as soon as you move the mouse onto it.

Expected behavior: Drawing on both, presenter screen and main screen are possible and are immediatly shown.

On Linux, drawing on the main screen is possible and works as expected. Still, drawing on the presenter screen also requires to move over the mouse to the main screen to let the drawings appear onto it as well. But I don't know if that's a bug or an intended feature...

To be clear, I have yet tested single screen mode.

If OpenGL is enabled, I can paint, but I have no context menu in running show. If I use Skia, then both painting and context menu work.

The original report was about "KDE Connect", further comments are about defects. Make a new bug about the defects or remove "enhancement" here?

Thank you so much it's working in LibreOfficeDev 7. I wish success to you and your team.

'Mouse pointer as Pen' annotation works as expected on recent master/7.2.0alpha bulds in both Skia and default GDI rendering. When set in advance of slide show, the annotations are kept and offered to save. When done with default settings, and activated by context menu during presentation, the annotations last for the slide show and are deleted on exit.

So this seems correct--and issue of OP is Linux. Is the KDE connect still an issue? Otherwise this is a => WFM

Is this a duplicate of Bug 62366?

> Is this a duplicate of Bug 62366?

I think it is not duplicate. This is about using "mouse pointer as pen" with OpenGL enabled on a single screen. Bug 62366 is about using "mouse pointer as pen" on the presenter console while another screen shows the presentation.
