<p>Thank you for reporting this. There is a missing dependency on the libxcb-xinerama0 package. Please install it with:<o:p></o:p></p>
<p> sudo apt install libxcb-xinerama0<o:p></o:p></p>
<p>and then try ChimeraX 1.2.5 again. This bug is also present in the current Ubuntu 18.04 and 20.04 downloads. It will be fixed within 24 hours.<o:p></o:p></p>
