Description Rainer Bielefeld Retired 2017-12-05 15:58:15 UTC
Steps how to reproduce with Version: (x64)
Build ID: a5af0fd9f27af42cf2e8571f659cdad6e606215b  CPU threads: 4; OS: Windows 6.1; UI render: default; 
TinderBox: Win-x86_64@42, Branch:master, Time: 2017-11-07_00:30:02
Locale: de-DE (de_DE); Calc: CL:

1. Open attached "sample_001.ods"
2. Click A1
3. <ctrl-c> for copy
4. Click Column Heading "B"
5. <ctrl-v> for paste
   Expected: after few seconds paste is done, can continue editing
   Actual: hangs for a long time, with maximum CPU loac                  :-(
           I had to terminate LibO after 15 minutes or so

a) All my tests seem to show that the problem is related to 
   conditional formatting, other cells without c.f. do not show this problem
b) Already REPRODUCIBLE with Version: 
   Build-ID: 22b09f6418e8c2d508a9eaf86b2399209b0990f4 CPU-Threads: 4; 
   Betriebssystem:Windows 6.1; UI-Render: Standard; 
   Gebietsschema: de-DE (de_DE); Calc: group
c) all the same on WIN10

d) With 
   I found possible DUP or 
   related to 
   "Bug 109280 - conditional formatting not preserved with copy paste operations"
Comment 2 Rainer Bielefeld Retired 2017-12-05 17:26:05 UTC
e) Already REPRODUCIBLE with Version: 
   Build ID: 63150712c6d317d27ce2db16eb94c2f3d7b699f8
   That underpins suspect concerning relation to Bug 109280
f) assigning a c.f. to a complete column via 
   menu 'format → conditionla formatting' does not cause a problem
g) I hope there is a workaround? In my universe a spreadsheet without
   possibility to spread c.f. to a whole column is completely useless.
(d): Oops, related Bug or DUP is "Bug 103312 - Using format brush to copy conditional formats to some rows generates thousands (?) additional conditional formats making the spreadsheet unusable slow"
