Bug ID: 520893
Summary: Stack Overflow crash in layout loop during large-scale
document workspace layout shifts and node activation
Classification: Applications
Product: krita
Version First 5.3.1.1
Reported In:
Platform: Microsoft Windows
OS: Microsoft Windows
Status: REPORTED
Severity: crash
Priority: NOR
Component: General
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
DESCRIPTION
Crash with StackOverflow when loading many documents. (in my case, loading many
recovered files during startup, but could just as well apply after startup)
Depending on the active renderer the crash surfaced in one of Qt5Gui.dll /
USER32.dll / dxgi.dll
STEPS TO REPRODUCE
1. Create/load like 20/30+ documents in the workspace, in my case multi-layered
(some have over 10 layers)
2. Do a minor action for each, wait for autosave. Then kill Krita in task
manager and restart it to trigger recovery Window. Leave all checked. Repeat
this process if needed, so the amount of different versions of the autosaved
documents increases to a point where loading them all during startup results in
the mentioned crash.
There may be other situations where it would not happen during startup but
simply loading an additional document where a lot are already loaded.
Autosaves stacking up in my situation in the first place came from another
problem where my current installation with the AI diffusion plugin is not
stable and makes Krita crash in unexpected moments too, but that is independent
of this issue.
OBSERVED RESULT
Crash with log entry in `kritacrash.log` in module (depending of the used
renderer:
Sometimes when it surfaces in `Qt5Gui.dll`, a stack trace is logged as well:
```
krita.exe caused a Stack Overflow at location 00007FFED29BF37E in module
Qt5Gui.dll.

EXPECTED RESULT
Documents loading without a crash or in case of insufficient heap memory for
those documents, graceful error handling which avoids limitless recursion or
event loops.
SOFTWARE/OS VERSIONS

ADDITIONAL INFORMATION
Possible cause(s)/analysis:
Subsystem Exposure Points:
Depending on the active graphics backend, document viewing mode, and lifecycle
stage, this exact same underlying structural loop surfaces across three
distinct system modules before breaching the thread stack frame limit:
Qt5Gui.dll!QTextEngine::itemize: The final native crash point when rendering
widget layouts and status bar string geometries
(KisMemoryReportButton::paintEvent) recursively under OpenGL or internal Qt
fallbacks.
USER32.dll: Flooded by un-throttled Win32 window resizing and grid-negotiation
messages when running in standard MDI Tabbed layout (mdi_viewmode=1).
dxgi.dll: Trapped during concurrent hardware-accelerated canvas context mapping
on startup when utilizing the default Direct3D 11 via ANGLE renderer. The
layout cascade causes a memory race condition while trying to spin up multiple
hardware-accelerated viewport swapchains simultaneously, crashing DXGI
asynchronously.
