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 Additional Info: User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:50.0) Gecko/20100101 Firefox/50.0
Created attachment 130650 [details] testcase, calc with many comments This bug was modeled after Bug 60418, after being told to open a new bug report, because the same behavior in calc is not the same as in writer. I mention this in case the code-base of comments might be similar and to make the history clear.

Áron pointed out that there is already a matching report. I will mark this as duplicate. However, even the test file in bug 76324 does not cause me problems. *** This bug has been marked as a duplicate of bug 76324 ***
hi, comments (notes, post-it's, captions) are! an issue, since years, and 76324 is the main bug for it, but making very little progress ... (it's too long for developers to read and recheck ) the provided sample has only about 250 comments, that shouldn't be a problem on recent hardware, but bigger amounts definitively are. there have been - accidental? - improvements in ver 6.2.7.1 and 6.2.8.2, win!, lin was still very slow. theese improvements seem to 'fade out' in 6.3, 6.4, 6.5 and 7.0 versions :-( i suggest using the 6.2 versions for files with plenty comments, be careful, they are not robust regarding parallelized computing, 'openCL' or 'threaded' enabled produces errors (needing hard recalc). if anybody knows how to find someone with skills to work an this annoying problem i'd appreciate it very much, this bug is already affecting fun with the program for too long time. reg. b.
