GNOME Shell 3.26.2<br>
geany 1.33 (generated on 2018-03-06  with GTK 3.22.28, GLib 2.54.3)</p>
<p>The issue is present also running <code>geany -c /nonexistent/folder</code>. I am encountering exactly the same problems described by <a class="user-mention" data-hovercard-user-id="36872080" href="https://github.com/bentref">@bentref</a>.<br>
I can confirm it is not CPU related.</p>
<p>I am using geany since > 5 years and I have never experienced anything similar.<br>
If there is anything I can do, I'll help gladly.</p>
