CentOS 7 - Fontsize gets uncontrolled bigger

[willi1166]

Hi,

I have an issue regarding a running server with CentOS7 and Tigervnc.
While using tiger vnc the font size gets suddenly bigger. There is no regular pattern, it just happens. While the font size in dolphin is huge the font size
of the application launcher remains regular. The set system fontsize remains constant in the settings menu. The only way to fix it is to restart the vnc client. Is there any other way or hint how to prevent this issue ?

Thanks in advance
