            Bug ID: 131340
           Summary: calc: while parallelized computing (openCL and
                    'threaded') is still buggy reg. autocalculate: mark it
                    as experimental and switch default 'off' for new
                    versions
           Product: LibreOffice
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Calc

Description:
the headline say's it all, imho a feature with known bugs shouldn't be on by
default, and users should be informed about the risk when activating it. 

it affects e.g. bugs 124577 and 129753, stacks of 100+ cells sometimes produce
wrong results on copies into the second cell from top. 

there are others like 98009 and 103532 up to now only 'solved wfm'. 



Steps to Reproduce:
1. check above mentioned bugs, 
2. see errors occuring with any parallelizing option enabled, 
3. see errors need recalculation, 
4. see errors re-occuring on sensitive actions after recalc, 
5. see errors hard to spot for normal users, 
6. i suggest to protect users from running the risk of such miscalculations
without warning

Actual Results:
wrong results until manually triggered recalc, 

Expected Results:
correct results, autocalculate working as announced, 


Reproducible: Always


User Profile Reset: No
