Ruffle freezes when loading any swf

[kreudom]

Describe the bug

When trying to run any swf file in Ruffle, nothing is displayed and the window freezes, sometimes causing the whole desktop to freeze for a while.

Ruffle runs without any problems if I launch it without specifying a swf file, but as soon as I try to load one, Ruffle freezes.

When I specify a swf file as a command line argument, Ruffle freezes immediately.

The freeze happens on every swf file I tried, even on Ruffle's test swf files (like tests/tests/swfs/avm1/add/test.swf).

I tried both the latest nightly release and building from source.

Expected behavior

Ruffle should be able to open files without freezing.

Additional information

I used git bisect to track down the first commit that doesn't work for me: 2dcd783

I further narrowed down the issue: The previous commit works. If I update wgpu-hal to 0.17.1 using cargo update -p wgpu-hal, the freezing occurs again.

I then used cargo's patching mechanism to track down which wgpu commit of the 0.17.1 release introduced the issue. This is the first commit that causes the freezing for me: gfx-rs/wgpu@1d0a22b

I confirmed that Ruffle does not freeze on the latest commit if I revert gfx-rs/wgpu@1d0a22b.

I am not sure if this is a bug in Ruffle or wgpu, but I figured I'd report it here. Let me know if you need any additional information.

You should probably report this to wgpu on their repository page. If the issue was caused by a regression in wgpu, then we can't fix it.

Fixed in wgpu 0.17.2

It would just need to be merged into your ruffle-rs/wgpu fork
