<p>ChimeraX was compiled on "CentOS Linux release 8.5.2111", but
that is extremely unlikely to matter.<br>
</p>
<p>The main GUI change between ChimeraX 1.4 and 1.3 is that ChimeraX
1.3 uses Qt 5 and ChimeraX 1.4 uses Qt 6. So, from your original
description, the most likely bug is that we missed a dependency
that is needed for Qt 6 to work. So you should try installing Qt
6 separately from <a class="moz-txt-link-freetext" href="https://www.qt.io/download">https://www.qt.io/download</a> (eg., get the open
source version's Qt Online Installer), and see if that fixes the
problem.<br>
</p>
<p>But you also mention trying to run ChimeraX by logging into a
remote system running RHEL 8.6 from RHEL 7.9. Running ChimeraX
remotely frequently fails to work. Officially, that is not
supported. There are too many possible points of failure. It
does work sometimes, and especially when the local and remote
system are running the exact same version of Linux and have the
exact same graphics driver installed. The graphics driver is the
usual culprit, and that can be mitigated by running ChimeraX under
VirtualGL on the remote system.</p>
<p>For completeness, if you are stuck with a RHEL 7 desktop, and
your data is on your local system, you could run ChimeraX in a
virtual machine. So instead of logging in via ssh, you startup
the virtual machine, and login to it directly. Some virtual
machines are better than others. I've been happy running
different flavors of Linux on VMware Workstation Player on a
Windows desktop with a Nvidia GeForce GTX 970 (remember to enable
3D graphics support). There is also a Linux version of VMware
Workstation Player.<br>

<div>Dear ChimeraX developers,</div>
<div><br>
</div>
<div>I installed ChimeraX 1.4 (both stable release and daily
built) on RHEL 8.6 and 9.0. <br>
</div>
<div><br>
</div>
<div>I installed all the ChimeraX 1.4 dependencies using
"yum install" from RHEL installation USB.<br>
</div>
<div><br>
</div>
<div>After the installation, I was able to start the GUI,
but unable to click any button on the GUI, therefore, I
was unable to report the bug from the GUI either.<br>
</div>
<div><br>
</div>
<div>I also tried ChimeraX 1.3 stable release on RHEL 8.6,
and everything was normal.</div>
