            Bug ID: 130381
           Summary: Calc: max. cpu load when defining 2 print ranges
           Product: LibreOffice
           Version: 6.4.0.3 release
          Hardware: x86-64 (AMD64)
                OS: Mac OS X (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Calc
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: hakuber at gmail.com

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
