Streetcomplete: In the achievements screen, illustrations are flickering

Created on 4 May 2020  Â·  3Comments  Â·  Source: westnordost/StreetComplete


When I open the achievements screen, illustrations are flickering.
It seems that the different illustrations interfere with each other.

Here a screen capture of the behaviour : https://cloud-lstg.yourownnet.fr/s/Z9XgipXbSorwCiT

How to Reproduce

Open the achievements screen and it happens.
(I guess that you must have some achievements)

Versions affected

Android 9
StreetComplete 19 (from F-Droid)

There is a bug here — two bubbles should never overlap each other. It looks like either the bubbles are being created too large (no room to show them all without overlapping), or collision detection is not working properly.

I am not sure if this is a bug in streetcomplete or jbox2d.

Heh, it's not flickeriing but the physics simulation. The big bubble is pressing the one into the corner so that little bubble is under very high pressure to get out but can't.

I am not sure if I can do anything about it. You could fling the one bubble upwards so the smaller has some more space.

Oh ok... I didn't get that those were bubbles and you could move them around :D
