MT4 & Linux: Windows Fonts are not visible on MT4 suddenly!

Hello Linux-people,

suddenly all Windows Fonts are not visible on my MT4.
Instead Rows and other signs there are rectangles only on screen.
PC has Linux Mint 18.3 Mate.

MT4 runs under WINE since 2016 on this Home-PC
all Windows Fonts and 2 DLL-Files were copied from Win7 to .wine orders
and it worked perfectly till October 2018.
May be an Update in October broke Wine ....
I have made a new installtion wine and MT4,
no chance.......
It does not work correctly

I have a Notebook with MInt 19 Cinnamon,
WINE & MT4
there are no such Problems here.

Thanks for your Help
