Bug ID: 159131
Summary: Calc v7.5 is laggy when moving a line (row)
Product: LibreOffice
Version: 7.5.9.2 release
Hardware: Other
OS: Windows (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Calc
Assignee: [email protected]
Reporter: [email protected]
Description:
The latest version of Calc has becomed laggy when : select a complete row, move
it down or up by "grabbing" a cell with the mouse : this simple operation takes
1 or 2 seconds. On the same pc, version 6 does the same operation instantly.
It's laggy even if the spreadsheet is empty.
A columns move on version 7 is not affected by lag.
All this clues indicate that the high number of columns (16384) could be the
cause of the lag.
Do you think, dev. people, that an option could settle this lost of
performance? I'm not sure that a total number of columns could be set/chosen,
because it surely would be a mess with compatibility...
But I'm interessed about it. Thanks for your attention
