Problem and solution are described here – http://community.jaspersoft.com/jaspersoft-studio/issues/7626

You must find “runubuntu.sh” script in Tibco Jaspersoft Studio directory and all line “export SWT_GTK3=0” before start of studio.

Content of the file should look like follows:

#!/bin/bash
export SWT_GTK3=0
DIR=$(dirname "$0")
export UBUNTU_MENUPROXY=0;
"$DIR"/Jaspersoft\ Studio $*
