Summary: High CPU usage during row/column selection in Calc
Severity: normal
Classification: Unclassified
OS: Windows (All)
Reporter: psce7cjk-v437s...@yahoo.com
Hardware: x86-64 (AMD64)
Status: UNCONFIRMED
Version: 4.3.0.4 release
Component: Spreadsheet
Product: LibreOffice

A kind of screenshot
Hi,
Selecting multiple rows and/or columns in Calc eats lots of CPU (100% of one
logical CPU to be more precise).
To reproduce this:
- open any project in LibreOffice Calc;
- select several rows and/or columns with mouse left button clicks and keyboard
Ctrl button pressed;
- look at CPU usage;
- continue selecting;
...
- sadly, no profit.
The larger the selection is, the longer the high CPU usage period is.
The process thread is "soffice.bin!main+0x153".
This has been tested on Windows 7 both x86 and x64 using three different
hardware setups. The screenshot is taken on a quad-core x64 system.
This is the behavior of all the "fresh" versions since 4.2.0.x so far.
Versions 4.1.x are this-bug-free.
Thanks in advance,
Artem
