Description Hans 2020-02-03 11:38:01 UTC
Description:
FORMATTING, PRINTING, Print Ranges:

When a 2nd print range is defined on the same sheet of a Calc Spreadsheet, the CPU load goes up high and doesn't recover. 
Applies only to 6.4.0.3.
It doesn't happen in 6.3.4.2 and earlier versions.


Steps to Reproduce:
1. create a Calc Spreadsheet (can be empty)
2. define a print range on the sheet (CPU load OK)
3. add a 2nd print range on the same sheet (CPU load maximizes and doesn't recover)

Actual Results:
Print range #1 defined: CPU load OK.
Print range #2 added: CPU stuck at high load.

Expected Results:
CPU to run at normal loads with 2 print ranges, like having only one print range.


Reproducible: Always


User Profile Reset: No
