<p>FYI, if you have Radeon graphics, the very latest Radeon driver
fixes the problem. It is in Radeon Software Adrenalin 21.4.1 from
20 April 2021. The Windows display driver is version
27.20.21002.112.</p>

Hi Hua,
<div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>FIrst,
does your machine have a Radeon graphics card? The latest
Radeon drivers are buggy and don't work with Chimera so if you
have a Radeon card you will have to roll back to an earlier
version of the driver.</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>If
you don't have a Radeon card, the fact that the debug info
indicates that you were "initializing graphics" strongly
suggests it is a problem with whatever graphics card you do
have, so I would need more information about your card and
driver version. If you don't know that information you can get
it by running the "dxdiag" program. Type "dxdiag" into the
Windows search bar to find it. When you run it you might be
asked if you want to check if the drivers are WHQL certified,
but that is not important for Chimera. Then click on the "Save
All Information" button, which will create a text file with all
of the information. We are only interested in the System and
Display tabs. Then send that file to me.</div>
