Code in tJava not readable

[demikbra]

Hi,

I have a very strange problem that i can't get to solve. After moving to another computer the code in the tJava components is not readable. Only rectangles are displayed (see Screenshot). If I copy the characters into an editor it looks good.
I have no idea how to solve this. Does anyone have any tips for me?
System: openSUSE Tumbleweed 15.1 with KDE Plasma, Java8 and TOS7.2.1

Many greetings

Mike

OK, I have not found a solution. So I changed the OS. Now I use LinuxMint 19.3. Everything goes well here.
