<p>The problem isn't a missing shared library. Using ldd on the
shared libraries doesn't find anything missing. And if you don't
blink on a slow computer, you can see the contents being drawn and
then written over so it's blank. And if you install PyQt6 and
PyQt6-WebEngine into a current daily build, then it works.</p>
<p> sudo /usr/libexec/UCSF-ChimeraX-daily/bin/python3.9 -m pip
install PyQt6 PyQt6-WebEngine</p>
<p>Well, the file history and log widgets are correctly drawn. I
still have an OpenGL issue running Fedora 35 in a VM:</p>
<p> QWaylandGLContext::makeCurrent: eglError: 3009, this:
0x37918d0</p>
<p>and that is fixed by turning off wayland in /etc/gdm/custom.conf
and rebooting.<br>

Hi Greg,
<div class=""><br class="">
</div>
<div class=""> This is just the Qt window toolkit html panels
such as the Log failing. Qt renders each of those panels from a
separate process and it seems likely that separate process
simply fails because of a missing system shared library. Have
you looked to see which needed shared library is missing, since
it could perhaps just be installed on the newer Fedora to make
ChimeraX work?</div>

class="">Yes, the problem is that your operating system
is too new :-). You will need to wait for a newer
version of ChimeraX that uses Qt 6 instead of Qt 5.
Fortunately, we are working on that right now, and there
should be a version available within a week. It is a
major change, so it will be in a "technology preview"
build before it shows up in the daily builds.
Unfortunately, ISOLDE doesn't work with daily builds.
So you are effectively stuck until there is a ChimeraX
1.4 release and ISOLDE is updated for 1.4.</div>

class="">In the interim, you might be able to run
ChimeraX in a singularity or docker container that is
based on Fedora 33. Or it might work in a virtual
machine. I think a singular container version would be
best (most efficient and performant), especially if the
graphics driver is the same version as the one in the
host OS. But I've been pleasantly surprised with how
well ChimeraX graphics works on a Linux VM running in
VmWare Workstation on my Windows desktop.<br class="">

getting started with ChimeraX. I installed the latest
production release (Centos 8
version, ucsf-chimerax-1.3-1.el8.x86_64) on my Fedora
33 workstation. It worked great. I installed Isolde
and Clipper through the help viewer winder and
everything was great. Yesterday I upgraded the
operating system to Fedora 35, and now the help viewer
no longer works. It is just blank. I can't get it to
show other web sites, files from my hard drive -
nothing. I installed ChimeraX on 3 other workstations,
and all have the same problem. This is very curious
and there is no error output that I can find to help
point me to the problem. Has anyone else experienced
this?</div>
