Bloc: Ominous Black External Window

Everything was working "okay" (although the examples seemed very slow to respond). Then, without apparent cause, now BlBasicExamples>>exampleGeometry (and all the other examples I tried) show a native window with blank (black) contents. Why is that happening and how does one debug something like that? Thanks.

Hi Sean,
i know you are on mac but what is the Bloc version you loaded?
If it is the 0.11, there are some issues with OSWindow on mac, does the problem temporarily gone when you relaunch your image?
On the master branch, we currently don't use OSWindow abstraction but only the SDL2 binding. This fixed some issues we had on mac, so, tell me if you face the same issue with the master branch.

Else, if you face some unexpected behaviors,  you can first try to evaluate "BlUniverse reset".

Regards,
Glenn.

IDK. I loaded via: "Metacello new baseline:'Bloc'; repository: 'github://pharo-graphics/Bloc/src'; load:#core".

That corrected the problem. Thanks.

Hi Sean,

Great.

Could you describe the situation and the concrete path that fixed it for you so that we can extend the instruction on the GitHub page?

Cheers,
Doru

There was no clear cause. While playing with the examples, suddenly when Bloc opened an external window, the contents were black, and existing windows were uncloseable via the title bar button.
