If WARP is not used, stdout causes a crash and leak when RDP is disconnected (deadlock in `ControlCore::SizeChanged`)

[TGSAN]

Windows Terminal version

1.15.2002.0

Windows build number

10.0.22622.450

Other Software

ffmpeg 5.0

Steps to reproduce

1. Use RDP(mstsc/msrdc) to connect the remote Windows (Physical graphics card already installed).
2. (In Remote) Open Windows Terminal 1.15.2002.0
3. (In Remote) Continuous live streaming or media format conversion using ffmpeg in Windows Terminal. (Because ffmpeg continuously outputs the current state via stdout)
4. Disconnect RDP.
5. Wait a while.

Expected Behavior

No response

Actual Behavior

1. Windows Termianl and running command line programs can crash.
2. If RDP is disconnected for a long time (e.g. several hours), it will exhaust the system resources and render the operating system unusable
3. If "Use software rendering (WARP)" is turned on in Windows Termianl settings, this problem does not occur (it is suspected that GPU rendering tasks are piling up after RDP is disconnected, but cannot be processed)

Hmm. This sounds like the #12607 hang/crash, or at least some variation on it (a la #13386). That's a great observation that switching to software rendering works as a workaround. That would get out off the GPU, preventing the deadlocks via GPU driver code calling back to the main thread.

I'd love to get a dump of the terminal in this hung state from you if at all possible. We've got two different sets of hangs possible now - I'd love to have a solid confirmation that what you're seeing matches one of those signatures. If not, well then, that's just another mole we'd have to whack 😄

(maybe also related: #12176)

[zadjii-msft]

Can you repro this with the Feedback Hub for me? I think that'll get me a dump that I can use to positively dedupe this with one of the other crashes we got around here.

Hi there!

Can you please send us feedback with the Feedback Hub with this issue? Make sure to click the "Start recording" button, then reproduce the issue before submitting the feedback. Once it's submitted, paste the link here so we can more easily find your crash information on the back end?

Thanks!

I just reproduced this bug and submitted it via Feedback Hub, the link is here: https://aka.ms/AAhp3pr

INTERESTING. This is a different deadlock. it's in SizeChanged, but it's decidedly not #12176. That issue is a crash in teardown. This is a deadlock?

I don't think we've had the renderer deadlock come through nvwgf2umx_cfg!cask::SafeEnum<cask::md::Algorithm_ENUMCLASS_SCOPEWRAPPER>::operator=+ yet. Okay, well, I can't dedupe this then 😕

When I was documenting this issue, I may have actually had a deadlock after disconnecting from the RDP (unable to select the terminal text via the mouse pointer) and I ended up modifying the window size. I'm not sure if this action is what caused the SizeChanged to become deadlocked.

My steps:

1. Disconnect the RDP connection
2. wait for a while
3. reconnect to RDP
4. found that the stdout output of the terminal is no longer updated
5. tried to select the terminal text with the mouse pointer, found no response
6. tried to change the window size, but the word "not responding" appeared

I can reliably reproduce this one as well. I don't know if it's significant but I believe that the DPI of my devices is different

[zadjii-msft]

Folks that are seeing this reliably - can you try out Terminal Preview 1.16 with the new atlas renderer enabled, and check if this still repros the same?

They have different renderer paths, so it might alleviate this issue. You can install Terminal Preview side-by-side with Terminal (stable), so don't worry about being on Preview permanently.

[MihaZupan]

I ran into the same issue and can no longer reproduce it with the v1.16.264 preview, thanks!

[megapro17]

Unreleated, but i had the same hang after rdp with google chrome. Reinstalling win seems fixed it

[lhecker]

This will most likely be fixed by #14959 because it doesn't call any graphics APIs while the console lock is being held.

[zadjii-msft]

Anyone still seeing this on 1.18 Stable & 1.19 Preview/?

[zadjii-msft]

@megapro17 Hey since you're bumping this thread, does that mean you're seeing this on 1.18/1.19? Which version exactly?

Honestly if you are, it might be best to start a new thread about this. Our locking has changed substantially over 1.18&19, and I wouldn't expect the stacks from before to still be relevant. We'd probably need a new stack trace.
