Comment 1 Bart 2020-05-02 12:55:52 UTC 
With Linux/Debian10 and LibreOffice versions 6.1 through 7.0, Ctl-Z took 2 to 8 seconds. 

LibreOffice version:
   6.1 : 8 seconds
   6.3 : 2 seconds
   6.4 : 2 seconds
   7.0 : 2 seconds

it seem quite fast to me.

@Telesto, could you please test with an older version and without skia ?

45 seconds with

Comment 4 Telesto 2020-07-03 18:07:35 UTC 
Sorry 10 seconds.. 
The slowness is more related to selection of the full table + scroll (that really slow part)

Above found in
7.1

6.0

but not in
Versie: 5.2.4.2 
Build ID: 3d5603e1122f0f102b62521720ab13a38a4e0eb0

-> Hope you don't mind recycling this bug
Comment 5 Dieter 2020-09-25 06:42:38 UTC 
Telesto, what happens, if you test without Skia as requested in comment 2?
Comment 6 Buovjaga 2020-12-30 16:58:07 UTC 
I tested the table selection + scrolling in 7.0.4 on Arch Linux and then 5.0 in an old Ubuntu virtual machine and to me the slowness is the same
