Description:
>From LO 5.1.6.2 no version useable.
Spelling check slows system down, CPU load is increasing very strong (+50%).

It looks like bug #80042 - but that was based on Calc, this is Writer.



Steps to Reproduce:
1. complete uninstall  + re-install any version 5.2.* or 5.3.* - makes no
difference
2. using other language pack EN instead of NL with EN document to check - makes
no difference
3. complete uninstall previouss versions + re-install 5.1.6.2 - problem gone

Actual Results:  
upgrading on this system not possible

Expected Results:
downgrading seems to be only way to keep LO working on theis system


Reproducible: Always

User Profile Reset: Yes - and deleted *all* LO files/directories

Additional Info:
changing OpenCL / OpenGL settings  doesn't help
