Comment 1

[Erich Gubler [:ErichDonGubler] (he/him)]

This is an OOM error, so…unless we're using resources really inefficiently, I'm not sure that this bug is actionable.

Comment 2

[Teodor Tanasoaia [:teoxoy]]

We are explicitly panicking since we didn't expect VK_ERROR_UNKNOWN to be returned.

VK_ERROR_UNKNOWN will be returned by an implementation when an unexpected error occurs that cannot be attributed to valid behavior of the application and implementation. Under these conditions, it may be returned from any command returning a VkResult.

Note
VK_ERROR_UNKNOWN is not expected to ever be returned if the application behavior is valid, and if the implementation is bug-free. If VK_ERROR_UNKNOWN is returned, the application should be checked against the latest validation layers to verify correct behavior as much as possible. If no issues are identified it could be an implementation issue, and the implementor should be contacted for support.

Judging by its description it sounds like we should turn it into device loss, if we are bug-free ourselves.

It would be nice to have a reduced stand-alone test case for this.
