Altitude/speed graph quirks

[marcs]

Hello,
I noticed some strange behaviour on my Xiaomi Redmi 6.
When I record a track and look at the details, the altitude/speed graph is not shown and a message "Not enough data" appears instead. If I tap on the button "full screen", then the graphs appears.
The cursor on the graph do work with a long delay (maybe 2 seconds) and move so strangely that they are barely usable.
Thanks

Hi again,
Would you mind to email me the .trk file of that track? (contact at psyberia dot net) Thanks in advance.
If you disable "Noize reduction" in the stats settings (see here), do you see the graph? If so then it means that the GPS signal is so inaccurate that it can be used...

Hi,
For those that may have the same problem:
The cause for the bad behaviour was a developper option that was enabled: Force GPU rendering.
Once disabled everything works fine again.
