[seb]

When playing the Game with 7 AI players the games crashes after about 10 minutes on Alpha 24. (0.0.24b) Relevant trace:

Can you attach the logs and your system info, please? wiki:GameDataPaths

[seb]

Are those files that sufficient or you need something else?

[Langbart]

You could also take a screenshot Shift+cmd+4 of your options and attach it here. Also you could test an upcoming A25 version (​Fifth RC - Revision 25848) and see if the problem can be repeated there.

PS: You have got an 2018 '15inch Macbook Pro can you see the polygon (see #6113)?

[seb]

Which options do you mean exactly?

[Langbart]

Replying to seb:

Which options do you mean exactly?

"Settings->Options->Graphics"

[seb]

Grafic settings are default. Version 25 crashes even faster. Same stacktrace with the CRenderer. It happens on the map egypt 3x3.

I can see the polygon though :-)

[Langbart]

Check this ticket answers regularly, maybe ​vladislavbelov has some questions or even a solution for you to answer/check.

Replying to seb:

I can see the polygon though :-)

Thanks for testing.

[Langbart]

I can also reproduce the problem. The map crashes in A24b and works in A23b. Both times I used the default graphics settings.

PS: The removed visibility of all shorelines is not a bug, but was actively removed with patch [24687] (18/Jan/21).

When running lldb I get this for the SVN version [25848] when crashing:

The crash happens for me as soon as I move the camera towards 5 o'clock, if I don't move the camera at all it doesn't crash.

[Langbart]

I have disabled all graphics setting (general+advanced) one by one and restarted the map each time, but the crash never stops. It always happens as soon as I move the camera towards 5 o'clock.

[Langbart]

Good ​IRC 0ad-dev (5/Aug/21) conversation:

17:48 < Langbart> Stan I never had "GLSL" enabled because I started with the default settings and then started disabling stuff. When I turn on GLSL, I no longer crash.

18:07 < Vladislav> Ok, I got it.
18:07 < Vladislav> Might be fixed in A26 or just forgotten.
18:07 < Vladislav> ARB shouldn't be.

[Langbart]

With Alpha 26, this problem should no longer occur.

In [26069]: (14/Dec/21)
Replaces unclear PreferGLSL by direct renderer backend choice.
