nuklear-test's Issues

Error while building.

Trying to build it. And when I run: "cargo build" I get this errors;

Segfaults on window opening

Mac OS X 10.11.2

Ran the program with cargo run.
The window takes around 10 seconds to open.
When it does, this is spit out.

error: An unknown error occurred

This is a segfault (signal: 11, SIGSEGV). Do you have any idea why this might happen?

wgpurs branch freezes on Windows when selecting an item in the combo box

The freeze appears to be caused by display list corruption. I can reproduce this on Windows 10 just by selecting an item in this combo box. It does not freeze if the dropdown menu is closed by clicking anywhere else, for example. I've tried to create a minimal repro case, but it's too easy to change the behavior just by adding or removing widgets.

I can pause the executable in the VS debugger while its frozen. The nk_foreach() inside nk_convert() never breaks. The latter is called here, in the backend: https://github.com/snuk182/nuklear-backend-wgpurs/blob/42d85b916dbaee2d3ffcf640cd426dee3280ee9c/src/lib.rs#L254 And the former is internal to nk_convert(): https://github.com/vurtun/nuklear/blob/509c75b086351e82865f26a507235b60a63e1538/nuklear.h#L10341-L10458

This looks like display list corruption because I can see an obviously bad cmd->type while the display list is iterated inside nk_convert(), which falls into the default case and the iterator repeats from the beginning, endlessly.

I haven't been able to track down the source of the corruption. Part of the problem is lack of useful tools on Windows for tracking down undefined behavior. And because I cannot reproduce this behavior on macOS, I can't make use of the clang sanitizers to debug this. (I ran the C++ example with the sanitizers on macOS, but found nothing out of the ordinary. Couldn't get the Rust version to build with sanitizers though.)

This only happens on the wgpurs branch; I've also tested gdi, glium, and dx11 on the same Windows machine without trouble. The freeze does not happen at all on macOS in the wgpurs branch.

Error when run the built program

cargo run works, but there is error when run the program manually after cargo build.
