@jmoguill That's something we want to improve on by providing better error messages. There are some challenges related to tracking a lot of state by syncval, but this aligns with...
It looks like it's not a regression from the recent changes. I tried to build locally VVL snapshots up to the previous SDK and all of them reproduce the issue,...
Let me check it during this week
@spencer-lunarg the investigation with the latest VVL (Debug/Release/RelWithDebInfo builds), but also with SDK 1.4.309 and the SDKs after SDK 1.3.290.0, suggests that the problem fixed itself. No crashes.
It's confirmed now https://gitlab.khronos.org/vulkan/vulkan/-/issues/3980#note_498278
@carnaval exactly , we usually disable validation in this case, since we don't have enough information. Yes, this is probably a missing check for external semaphore.
@carnaval the issue description also says that syncval is enabled (detection of race conditions). This error looks like a core check issue. Could you check if the issue reproducible with...
Few more questions to understand the problem: a) What's the full error message? b) Does the app use host side semaphore functions (vkWaitSemaphores/vkSignalSemaphore) for the sync mechanism described in the...
I'm also not quiet sure how the above error is possible, so far it's not obvious if we need the check for external timeline semaphore as we did for binary...
@carnaval thanks for the provided details, I'll check them tomorrow.
