[pett]

Apparently remote display, though nothing particularly indicative of graphics problems in the report.

[Tom Goddard]

The Log is clearly incomplete since it doesn't show opening any data. Linux users can easily run multiple ChimeraX instances at once and the caching of the Log for reporting crashes won't work correctly in that case since all use the same Log cache file.
