Spark 2.6.3 BlueScreen problem

Hi Everyone.

One month ago I implemented the Openfire / Spark in our company (one Openfire server, about 60 workstations).

Everything works fine except some workstations. All workstations are using Windows (XP or 7).

I have bluescreen problem. I tried to update video drivers, java to latest 7 Spark.vmoptions with this lines:

-Dsun.java2d.d3d=false

-Dsun.java2d.noddraw=true

-Dsun.java2d.ddoffscreen=false

Nothing helps

Anyone could help me how to trace where’s the problem and how to solve it??
