Presentation with a slide with 2000 shapes
When copy/pasting a slide with multiple shapes in Ubuntu, the UI freezes for a long time.
I attach a file with an empty slide and a second slice that contains > 2000 shapes (1000 triangles and 1000 circles). If I copy/paste slide 2, the UI freezes for a long time. For more complex documents, the time increases considerably.
LO 22.214.171.124: 1m 52s
LO 126.96.36.199: 1m 18s
Also, if I dare to try to select and copy all the shapes in the slide, the whole computer freezes and becomes unusable.
I believe that a similar document was handled significantly better in LO a few years back (~2013).
If I do the same operation in a VM with Windows 7 and Microsoft Office 2013 (.odp, .ppt or .pptx), the copy/paste or selection is almost instantaneous. Interestingly, when I save in LO the .odp file in .ppt/pptx, the 29MB file becomes a 1MB file.
1. I opened attach file in LO 188.8.131.52 on Windows 10 and tried copy/paste slide with many shapes. I have about 3-4 sec for paste new slide!
don't confirm long time paste of slide on >>>Windows 10<<<.
2. Really, if save ODP to PPTX, then size of file will be VERY small (about 1 mb)! And this PPTX opens fine in LO, it has all shapes and photo of man in right-bottom corner of slide.
I'm not getting the slow times as the reporter, but they are slower than in previous versions.

they are about 8-10 secs and undo something similar.

@ Gorka Navarrete
Which version of Ubuntu & Libo downloaded from libreoffice.org or Ubuntu repro?
@Telesto, The times I reported are from a 2 years old Ubuntu 16.04 HP workstation (Xeon proc, 16GB, SSD HD) in a Downloaded (from the web) LO 18.104.22.168 and 22.214.171.124 from the LO PPA: https://launchpad.net/~libreoffice/+archive/ubuntu/ppa
But this also happens in a i7-5600U 8GB SSD Lenovo laptop with ubuntu 18.04 using LO 126.96.36.199 from the Ubuntu repos, and in a third desktop i7 8GB SSD computer.
A part of the problem seems to be related with GTK3. Using sudo apt remove libreoffice-gtk* makes the time go down to less than 5 seconds in my laptop (from ~2 minutes).
Caolan, may be you are interesting in this problem?
Yep, gtk3 takes 8 secs for me while gen and gtk2 take a bit over 3 secs.
No idea where those 1 min+ times are coming from. Gorka: you should do a separate test by launching in safe mode, from terminal with 'libreoffice --safe-mode' or Help - Restart in safe mode and then Continue in safe mode.

it may not be gtk3 vs non-gtk3, it may be a11y enabled libreoffice vs a11y disabled one
Buovjaga, I tried starting from a terminal with libreoffice --safe-mode and times are still >1m.
With a i7-4790 (8GB RAM), Ubuntu 18.04, LO 188.8.131.52:
safe mode: ~1m40s
normal mode: ~1m37s
NO gtk3 (a11y disabled): ~2s
