Package: tuxguitar Version: 1.6.4+dfsg1-1 Severity: normal Tags: patch The embedded browser does not start if the libswt-webkit-gtk-4-jni package is not installed. After installing libswt-webkit-gtk-4-jni, the embedded browser window opens, but remains empty. Adding WEBKIT_DISABLE_COMPOSITING_MODE=1 to the startup script fixes this.
