Rpcs3: Crashes with MultiThreaded RSX when using Write Color Buffers/CPU Blit
Video
Log file for v0.0.6-8501-a0f0c418
Specification
RPCS3 v0.0.6-8501-a0f0c418 Alpha | HEAD | Firmware version: 4.84
Intel(R) Core(TM) i7-8700K CPU @ 3.70GHz | 12 Threads | 15.93 GiB RAM | TSC: Bad | AVX+ | TSX-FA
Operating system: Windows, Major: 10, Minor: 0, Build: 18362, Service Pack: none, Compatibility mode: 0
路! 0:00:00.000000 RSX: Found vulkan-compatible GPU: 'GeForce RTX 2070' running on driver 431.60.0.0
Notes
This can be consistently replicated with a fresh install of RPCS3. LLVM with all cache/dev_hdd1 and configs freshly created.
I have already troubleshooted in the #help channel on Discord to no avail. I am running the game using recommended settings. I have tried many different combinations of settings to see if it affects the freeze, but it would seem that nothing fixes it.
Thank you!

Try disabling RSX multithreading. I identified a potential deadlock bug with it recently but haven't yet pushed a patch for it, so it can actually cause the emulator to lock up.

By jove Sir, that was precisely the cause of the issue. I disabled RSX multithreading and bam, problem gone. Thank you so much for the recommendation. Looking forward to the patch!

@CaptainStarPaw Can you please test with https://github.com/RPCS3/rpcs3/pull/6377 to see if it fixes it for you when MT RSX is enabled?

@Asinin3 @kd-11 Thank you both. I noticed the PR is still open, is there an automated build available or would you require me to build locally?

It's at the bottom of the PR page under Show all checks; see AppVeyor details there if you are using Windows.

Unfortunately I am unable to replicate the run because it freezes almost immediately after it loads my save. This freeze occurs in the Nexus approximately 2-4 seconds after I can see my character and run around.
It has crashed both after it loaded Nexus and also during the load screen. The freeze sometimes occurs whilst it is "compiling shaders ..."

Can you rename this to "Crashes with MultiThreaded RSX when using Write Color Buffers/CPU Blit"? I'm pretty sure that it only affects games that are using Write Color Buffers or CPU Blit. Here's what I found with Modnation Racers:
Vulkan - Goes ingame fine, but graphics are broken without WCB
Vulkan+WCB - Goes ingame just fine
Vulkan+WCB+MT RSX - Crashes where the game used to crash (on loading screen right before the title-screen.
Vulkan+MT RSX - Goes ingame just fine except graphics are wrong due to no WCB.
https://github.com/RPCS3/rpcs3/pull/6377 did not fix the issue either.

Pushed a new fix, please confirm if it fixes the problems for you.

Yeah everything is fixed by the looks of it from a quick test, thanks!
