I am using RapidClipseX V10.2.2 on LinuxMint 19.03
Both are completely new and fresh installations

Eclipse Java Development Tools Version: 3.18.300
Eclipse Platform Version: 4.15.0.v2
Eclipse RCP Version: 4.15.0.v2

My Session Data:

eclipse.buildId=4.15.0.I20200305-0155 java.version=11.0.7 java.vendor=Ubuntu BootLoader constants: OS=linux, ARCH=x86_64, WS=gtk, NL=de_DE Framework arguments: -product com.rapidclipse.ide.product Command-line arguments: -data file:/home/user/rcx_ws2/ -os linux -ws gtk -arch x86_64 -product com.rapidclipse.ide.product

Are there any idea how to fix this?
