Thanks Heikki.
This is a problem with Google maps' new markers and an old version of
"chrome" used by some versions of PyQt5. Other maps should work OK.
I previously checked the chrome version and chose "legacy" markers if it
was less than 86. Then I found the
mapCapabilities.isAdvancedMarkersAvailable constant in the Google maps
API and assumed it would be false if using an old version of chrome.
Obviously that doesn't work.
I'll put a fix in the next release of Photini.
