LabelLayer breaks rendering

[MarsVard]

I have a map with 5 layers on it.

    mMap.layers().add(pathLayer);
    mMap.layers().add(new BuildingLayer(mMap, baseLayerOffline));
    mMap.layers().add(labelLayer);
    mMap.layers().add(userLocationLayer);
    mMap.layers().add(poiLayer);
    mMap.layers().add(eventLayer);

when I call startActivtyForResult() from inside the fragment where the map is, and then return to the fragment of the map. the labels layer is totally broken and messes up rendering of the map.

I tried removing the labels layer and that fixed it, I tried removing other layers and it was still broken.

I also tried removing the labels layer and then adding it back to the map, and it was still broken again.

is this a known issue? is there a way to bypass this problem?

Thanks for reporting. I haven't seen this issue yet. Could you provide a simple example for testing?

[MarsVard]

Hey @hjanetzek Here's a project that experiences the issue, it's a simple mock project with 2 activities.
https://github.com/MarsVard/BrokenMaps/tree/master

Hope you are able to provide more info or a way to fix this. and thank you for this awesome project.

[hjanetzek]

thank you. sorry, this week is kind of super busy - I'll get to it sometime next week

hmm - works for me with the latest vtm. I've changed vtm-0.5.9 to 0.6

[MarsVard]

I just updated to 0.6.0 and it's still happening but for some reason the first time I openend the first activity and went back it was still OK, then the 2nd time and after that the labels and map were broken.

all in the repository I posted earlier... and I also noticed this in logs:

27892-27928/com.marsvard.brokenmaps W/Adreno-ES20﹕ <__load_uniform_matrix:1091>: GL_INVALID_OPERATION

Is there a way to force map to reload? maybe if I force the map to reload when the activity resumes that will fix it ?

@MarsVard I found that it's caused by a texture used in the themes:
< style-area id="tex1" src="textures/rough.png" / >

When I removed it I got rid of the error.

[MarsVard]

@0nko do you mean the GL_INVALID_OPERATION or the rendering being broken?

[0nko]

@MarsVard yeah, GL_INVALID_OPERATION

[hjanetzek]

@MarsVard, 0nko the texture issue should have been resolved by the latest commit

@hjanetzek you're right, it works. thanks!
