Crash (native)

[AeroShark333]

Hello,


There are some issues with my app on some devices and I don't really know what's causing it...

The device is a Motorola Moto E with 4G (2nd Gen) running Android 6.0.
I can't reproduce this crash myself on any of my devices.

Maybe a kind of out of memory? The strange thing of, that it happens in Mali and on Adreno, which makes it look like an app related problem rather than an engine related. How often does it happen?

[AeroShark333]

Apparently this happens a lot and I managed to find a device with this issue myself (dad's phone).

Hmmm, I tried to mess around a bit and I'm starting to suspect the render target(s) or the blitting fragment shaders that I'm using.
The blitting shader is used for both rendertargets (in the blitting shader the shader is split for the two rendertargets)
In the heavy shader, render target 1 will do light operations and render target 1 will do heavy operations (probably too heavy for this phone).
In the light shader, render target 1 will do light operations and render target 2 will do even lighter operations.

One render target with a heavy blitting shader:
-> 4bpp enabled on render target (16-bit): Works. Works. Works. Works. Works.
-> 4bpp disabled on render target (32-bit): Works. Works.

Two render targets with a heavy blitting shader:
-> 4bpp enabled on render target (16-bit): Hangs. Hangs.
-> 4bpp disabled on render target (32-bit): Hangs. Hangs.

One render target with a light shader:
-> 4bpp enabled on render target (16-bit): SIGSEGV. SIGSEGV. Works. Works. SIGSEGV. Works.
-> 4bpp disabled on render target (32-bit): Works. Works.

Two render targets with a light shader:
-> 4bpp enabled on render target (16-bit): SIGSEGV. SIGSEGV. Works. SIGSEGV. SIGSEGV. Works.
-> 4bpp disabled on render target (32-bit): Works. Works. Works.

Or maybe it's not related to any of this at all...
I really have no clue...
Changing Config.blittingMode from 8 to 1 doesn't prevent the SIGSEGV from happening either.
This SIGSEGV doesn't happen on my own phone (which is more high-end...)

[EgonOlsen]

How large is the render target?

[AeroShark333]

On the phone I tried this on?
320x420 if I remember correctly (just the resolution of the screen in pixels)
I tried downscaling as well for the render texture (160x210 for example) but that didn't really change anything...

[EgonOlsen]

Can't be an OOM of some kind then. How does your pipeline (setting targets, blitting etc.) looks exactly?

[AeroShark333]

Something like this:

Code Select Expand

if (hasRenderTexture) {
this.frameBuffer.setRenderTarget(this.renderTexture);
if (hasBlitShader) {
this.frameBuffer.setBlittingShader(blitShader);
}
}
frameBuffer.clear();
~World render + draw~

Code Select Expand

if (this.hasRenderTexture) {
frameBuffer.display();
this.frameBuffer.removeRenderTarget();
if (settings.renderer_blit_shader_two_pass) {
this.frameBuffer.setRenderTarget(renderTexture2);
}
if (hasBlitShader) {
blitShader.setUniform(
EarthifyShader.SHADER_UNIFORM_TWO_PASS, 0.0f);
}
frameBuffer.blit(renderTexture, 0, renderTexture.getHeight(),
0, 0, renderTexture.getWidth(),
-renderTexture.getHeight(), frameBuffer.getWidth(),
frameBuffer.getHeight(), -1, false);

if (settings.renderer_blit_shader_two_pass) {
frameBuffer.display();
this.frameBuffer.removeRenderTarget();

// seconds pass
if (hasBlitShader) {
blitShader.setUniform(
EarthifyShader.SHADER_UNIFORM_TWO_PASS, 1.0f);
}
frameBuffer.blit(renderTexture2, 0,
renderTexture2.getHeight(), 0, 0,
renderTexture2.getWidth(),
-renderTexture2.getHeight(),
frameBuffer.getWidth(), frameBuffer.getHeight(),
-1, false);
}
if (hasBlitShader) {
this.frameBuffer.setBlittingShader(null);
}
}

frameBuffer.display();

[EgonOlsen]

Hard to track this one down...could be almost everything. Have you tried without VBOs? I doubt that it's related as this is clearly a texture thing, but one never knows...

[AeroShark333]

I tried that with Config.useVBO = false; but no luck there...

I tried to get some more logs (yeah, the screen resolution is bigger than I thought initially... I still don't think this would cause an OOM issue however):

I wasn't really able to reproduce this error on a non-4bpp render texture (maybe it never crashed then...) but on a 4bpp render texture it crashes about 90% of the time with this phone. (On my higher-end phone it does not crash with 4bpp enabled for the render texture).
So I initially thought the having 4bpp enabled on the render texture was the problem, though strangely... it does work sometimes (this 10%).
For now, I published the application with 4bpp disabled on the render texture and many users (who first got the crash) reported to me that it's working fine now...

Might be a driver problem of some kind or an oversight on my side, but I've no idea what it's supposed to be...

[AeroShark333]

Well apparently having a 4bpp render texture causes problems for me on older Andreno's and Mali's. A non-4bpp render texture pretty much solved everything instantly...

[AeroShark333]

Still getting these mysterious SIGSEGV errors..

Crash log #1: https://pastebin.com/xtCdy0Yk (line #141)
Working log #2: https://pastebin.com/9Ngvzg2Q (line #337)

So it seems that glDrawElements(...) is causing a crash here, although it is not always happening which I still don't really understand.

I tried to make it use glDrawArrays(...) by invoking build(false) and compile(false,false) but no luck there, same story: random crashes but sometimes works.

All textures do load, but when the first World draw call is made, it might crash.

EDIT:
Another unrelated question I always wondered about:
Why is TextureManager static and why isn't it designed in such way that you can have multiple TextureManagers (for multiple renderers)?

EDIT2:
I seem to be having issues with render target textures. Everytime I change device orientation I create a new render texture so it'd fit the rotated screen dimensions. However, I seem to be getting a memory leak here... How I do this:
-> start
-> on surface changed (): create rendertargettexture and add to texturemanager with a specific name
-> on draw (): use rendertexture
-> change screen orientation
-> on surface changed (): set rendertargettexture reference to null + unload&remove rendertargettexture using specific name + add new rendertargettexture with new dimensions
-> on draw (): use new rendertexture
While this all works fine, it seems to fill my device's memory if I keep changing the screen orientation.
Without using rendertargettexture, RAM usage might also increase a little when changing screen orientation but it'd get GC'ed and RAM usage will drop again.

Hello?

[EgonOlsen]

Sorry, I haven't spotted your question ealier. The upload method works only at render time, i.e. if you call unload, it doesn't really unload but waits for the next render call and then does the unloading. That's because it has to happen in the GL thread or otherwise, there's nothing to unload.
If you rotate the device, it might be that the actual context is already lost (or onDrawFrame not called anymore on it) so that the unload never happens but somehow the driver keeps the copy in memory (albeit it shouldn't, because it should be bound to the context and if that changes, it should go away).
If you sure to be in the right thread, you can try to set Config.unloadImmediately to true and see if that helps.
