I still do not know. I am using LO 3.7.5.2 on Xubuntu 13.04 right now.

That would probably mean to create a spreadsheet file with 100 sheets, each of
which with several hundred lines and several dozen columns. I refrain from
that. Or posting my original file - which I cannot do due to its content.

I mentioned it earlier in one of the other bugs I filed at the same time
(#53825, #53826, #53627, #53628, all of them probably not depending on this
bug), but I would like to point it out here again: My sheet does lots of
verification using conditional formats. Almost each of the million individual
cells has a conditional format, which is mainly used to set the cell's
background color depending on the cell's value. I do this as a visual
validation feedback. Many of these validations use lookups (german function
names "VERWEIS" or "SVERWEIS") or summation functions (german function names
"ZÄHLENWENN", "SUMMEWENN"), and I suspect a heavy impact here. Furthermore,
even with recalcuation off, validation seems to work partly (background colors
are updated, but inconsistently - I have not investigated further).

I am afraid I am not enough into LO debugging. Please let me know if my hint
regarding the conditional formats was of any use to you.
