<p>I am having the same issue after upgrading to Debian Sid (from Buster).</p>
<p>The workaround for me is to minimize bisq's window and wait until is fully loaded, then it is usable. Otherwise the whole system goes completely unresponsive.</p>

<p>Have you tried setting <code>_JAVA_OPTIONS="-Xmx512m"</code> ?</p>
