Description Matt Alexander 2021-10-31 14:41:15 UTC 
SUMMARY

At certain angles, the globe loses its green overlay and reveals the white background (see attached video).

STEPS TO REPRODUCE

1. Start copying several hundred photos into an empty album.
2. Open "Map" search.
3. Drag the mostly empty globe around.

OBSERVED RESULT

Sometimes the green overlay disappears and leaves just white land.

EXPECTED RESULT

Green overlay remains on the globe at any angle.

I cannot reproduce the problem here, probably a problem with your graphics card / driver. Can you reproduce the problem with the Marble application?

I cannot reproduce in either Marble or digiKam now. Perhaps there are some files to support that view that are cached now, but were being blocked from loading quickly during my import? It was the first time I'd opened that search pane since installing digikam.

Anyway, in case it's related to my display drivers, I've attached the output of `lspci` to this bug.
Comment 5 Maik Qualmann 2021-11-01 07:03:22 UTC 
It will probably be related to the loading of themap. If I delete the folder "~/.local/share/marble/maps", I can see the white earth for less than 1 second when calling up the atlas map under digiKam as well as under Marble. But no problems moving the earth. At the next start the earth will be green immediately. If so, you should report the problem to Marble. But what should Marble do as long as nothing is displayed until everything is loaded? Showing nothing is not a solution either.
