Wyse 3040 fail to refresh screen

Hi,
I have several client that experience program overlay issues where graphics from program aren’t refreshed/updated properly making grafics(text/icons) several of the programs at the back or mimimized to be visible in the foreground.

Fx. I write a letter in word, switch to outlook  and several places in outlook ca see the remains of the Word graphics.

 

Thisis only present in Wyse 3040 BIOS 1.2.5 ThinOS 8.6.013
