Screenshot with filter active, Windows 10 Home, 64bit

The issue is also reproducible on the following:

I. A new desktop PC with Intel Core i5-6400 CPU, 3.2GHz, cuadcore
Intel H110 chipset
4GB RAM (3.89GB available)
CPU-built-in graphics, 1920x1080 screen
Windows 10 Home 64-bit
LO Version: 5.0.5.2
Build-ID: 55b006a02d247b5f7215fc6ea0fde844b30035b3


II. A notebook from the year 2002
mobile AMD Athlon XP2200+

518MHz, 512MB RAM (448MB available)
Radeon IGP 320M graphics card
1024x768 screen

Tested with Windows XP Professional SP3, 32-bit
No Java installed
LO (LibreOfficePortablePrevious_5.0.5_MultilingualAll.paf.exe):
Version: 5.0.5.2
Build-ID: 55b006a02d247b5f7215fc6ea0fde844b30035b3


--------------------------------------------------

ADDITIONAL TESTS

Note: I'm going to use following PC configurations on these tests:
- Config 1: The Intel Atom N450 netbook from the comment 6 with Linux Mint 17.1
(original ISO as liveUSB), 64-bit

- Config 2: The above AMD Athlon XP2200+ notebook from this comment (point II),
with Windows XP Professional SP3, 32-bit

All tested LO versions downloaded from
https://downloadarchive.documentfoundation.org/libreoffice/old/


Tests:

A) Issue not reproducible / different issue

a) LO 3.3.0
- PC config 2 with LibreOfficePortable_3.3.0.paf.exe
OOO330m19 (Build:6)

tag libreoffice-3.3.0.4

=> There is a different issue: CPU load goes up on filter activation, but then
comes back down of itself after a few minutes

b) LO 3.5.3.2
- PC config 2 with LibreOfficePortable_3.5.3.1_MultilingualNormal.paf.exe:
LibreOffice 3.5.3.2

Build-ID: 235ab8a-3802056-4a8fed3-2d66ea8-e241b8

=> There is a different issue: File import takes ca. 10-15min, after which the
file is not displayed correctly - only column A is shown, while the rest of the
used columns is a white field.
Then as in the point c below.

c) LO 3.6.4.3
- PC config 2 with LibreOfficePortable_3.6.4_MultilingualAll.paf.exe
Version 3.6.4.3 (Build ID: 2ef5aff)

=> There is a different issue: Continuously elevated CPU load (around 65%)
after file import. The load goes down ("soffice.bin" at 0% CPU) when one tries
closing the modified (e.g. by filter activation) file and the "Save changes?"
dialog appears (which is canceled). No issue with filter activation after that.

d) LO 4.0.4.2
- PC config 1 with LibreOffice_4.0.4.2_Linux_x86-64_deb.tar.gz
Version 4.0.4.2 (Build ID: 9e9821abd0ffdbc09cd8c52eaa574fa09eb08f2)
- PC config 2 with LibreOfficePortable_4.0.4_MultilingualAll.paf.exe
Version 4.0.4.2 (Build ID: 9e9821abd0ffdbc09cd8c52eaa574fa09eb08f2)

=> As in the point c above.

e) LO 4.1.6.2
- PC config 1 with LibreOffice_4.1.6.2_Linux_x86-64_deb.tar.gz
Version: 4.1.6.2
Build ID: 40ff705089295be5be0aae9b15123f687c05b0a

=> As in the point c above.


B) Issue reproducible
a) LO 4.2.0.1
- PC config 1 with LibreOffice_4.2.0.1_Linux_x86-64_deb.tar.gz
Version: 4.2.0.1
Build ID: 7bf567613a536ded11709b952950c9e8f7181a4a

b) LO 4.2.4.2
- PC config 1 with LibreOffice_4.2.4.2_Linux_x86-64_deb.tar.gz
Version: 4.2.4.2
Build ID: 63150712c6d317d27ce2db16eb94c2f3d7b699f8


------------------------------------------------

SUMMARY

- The issue first appears in LO 4.2.0.1. The LO 4.1.6.2 is the last good one,
with a different issue (see next point).

- Appearance of this issue coincides with disappearance of a different issue:
continuous elevated CPU usage by "soffice.bin" (ca. 20% with PC config 1, ca.
60% with PC config 2) after file import, until a file closure attempt. So that
there may be a relation.
