Speed, location and compass jumping around, intensified by using OpenGL #20984

Description

I'm using OsmAnd for ~5-10 years and multiple devices and now I got a strange behavior I cannot explain or debug. Please see the attached short video clips.

Steps to reproduce

Just start OsmAnd and ride i.e. a bicycle. It does not matter if navigation is used or not or which profile is used. It does not matter if "Kalman filter" and/or "magnetic sensor" are enabled or disabled.

Actual result

Here you can see the jumping direction/speed using OpenGL rendering:

I tried it again using the old Version 1 rendering engine, which reduces the jumps a lot:

This is strange because I used OsmAnd on this device for months without problems using OpenGL. However I'm not sure if the behavior started after an OsmAnd update or after switching my OS from /e/ OS to LineageOS.

I also recorded the GPS status a day after that (the larger speed increase in the middle of the clip was on purpose), which does not show those extreme jumps:

Expected result

The speed and direction should be more or less steady and not jumping around.

Your Environment (required)

OsmAnd Version: 4.8.6 and Nightly 4.9.0#3347m (2024-10-03), same behavior
Android/iOS version: Android 14 (LineageOS 21)
Device model: Fairphone 5
Crash-Logs: No crash detected, but can supply i.e. logcat if required

The bug could not be reproduced. To reproduce the issue, navigate to coordinates 50.13968527663238, 8.669951027921593 and start bicycle navigation and try changing the settings for this profile.

As a result, there were no location jumps or icon jerking were observed during testing; navigation ran smoothly and without issues.

You can also try to disable the "Animate Own Position" option under Menu → Configure profile → General settings → Other → Animate own position. Additionally, please check if the issue persists on our nightly build: https://osmand.net/docs/versions/nightly_versions#nightly-builds.

OsmAnd~ 4.9.0#3416m, released: 2024-10-11
