Strange behaviour of pie diagrams in QGIS -- Pies "disappear" while zooming out

Question

I'm trying to create a pie diagram. But when I zoom in and out the pies disappear! See Attachment for the data? My mistake? Bug? Anyone?

Sorry, now with the correct video file...

Also see the whole project, as it might be a projection issue: https://politikvonunten.org/extern/project.zip

Please provide settings, as well as images of scale and map. — Erik, Commented Jan 2 at 16:15
Not able to download your file. Can you try another service, like WeTransfer, DropBox, etc...? — Pointdump, Commented Jan 2 at 17:01
Still can't download your data. Link asks me to "create account" and sign in. Please use WeTransfer, MEGA, or DropBox. And please add screen shots to your question. — Pointdump, Commented Jan 4 at 21:22
Sorry, file dowonload indeed does not work - we don't have the same view as you have on your screenrecord, so the video does not help. You seem to have an account. Without being logged in, it is not possible to download the data. Please provide the data in another way, as mentioned before. — Babel, Commented Jan 4 at 23:22
Sorry, here it should work: politikvonunten.org/extern/pie-diagram-points.zip — desputin, Commented Jan 5 at 7:34

Ok, this is the solution:

Repjoject all layers to EPSG:32633: - Vector --> Data management tools --> Layer reprojection
Then save all reprojected layers as new shape files
Create new project, import all reprojected shapes

Now it works.
