This prevents normal interaction with the material selection interface.&lt;\/p&gt;&lt;p&gt;I have already attempted the following troubleshooting steps:&lt;\/p&gt;<\/p>\n<ul>\n<li>&lt;p&gt;Resetting the UI layout&lt;\/p&gt;<\/li>\n<li>&lt;p&gt;Deleting the ANSYS AppData configuration folder (v252)&lt;\/p&gt;<\/li>\n<li>&lt;p&gt;Forcing software rendering using environment variables&lt;\/p&gt;<\/li>\n<li>&lt;p&gt;Changing Windows graphics settings to use integrated graphics&lt;\/p&gt;<\/li>\n<li>&lt;p&gt;Restarting the application and system multiple times&lt;\/p&gt;<\/li>\n<\/ul>\n<p>&lt;p&gt;Despite these steps, the issue persists.&lt;\/p&gt;&lt;p&gt;This appears to be a rendering\/UI bug specific to this version.
