Bug ID: 105499
Summary: Editing of .ods calc document with many comments
causes high CPU load, can crash on saving
Product: LibreOffice
Version: 5.0 all versions
Hardware: All
OS: Linux (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Calc
Assignee: [email protected]
Reporter: [email protected]
Description:
When a document as the attached, with many comments is opened then it can be
edited normally for some time. After some mouse-overs on the many comments and
some 15 seconds the document becomes sluggish and small edits like changing the
column width take up a lot of time and CPU skyrockets.
Editing a worksheet with many comments becomes actually impossible. Changing
the format of many cells or showing/hiding of columns can take minutes while
CPU/fan go crazy.
Sometimes LO crashes on saving, but only if the open worksheet is the one with
the comments, switching to another allows saving.
Steps to Reproduce:
1.open example document
2.mouse-over some comments in the worksheet, wait some seconds
3.try resizing the column width, CPU of one core goes to 100% for half a minute
Actual Results:
hight CPU load on almost any edit
Expected Results:
normal CPU load, independent of number of comments in worksheet
Reproducible: Always
User Profile Reset: No
