Description Ming Chuan 2025-09-30 04:03:58 UTC 
SUMMARY

When adding a layer style to a layer, after the layer style pop up appears, krita crashes randomly

In `BevelAndEmboss::fetchBevelAndEmboss`, `bevelAndEmboss->setTexturePattern(m_texture->ui.patternChooser->currentResource(true).staticCast<KoPattern>());` passed a `QSharedPointer<KoPattern>(nullptr)` into `setTexturePattern`. Perhaps the pointer it's casting from is already null?

The `KisSignalCompressor::slotTimerExpired`/`KisSignalCompressor::timeout` in the stack trace looks suspicious

STEPS TO REPRODUCE
1. Have some kind of complex krita files with multiple clone layers and filters, that already makes krita laggy
2. Add a new layer style to one of the paint layer
3. krita crashes, randomly

OBSERVED RESULT


EXPECTED RESULT


SOFTWARE/OS VERSIONS
Qt 6.9.2, with recent krita master.

Comment 1 Lenzoid 2025-12-20 22:12:03 UTC 
Thanks for the report. You filled Version First Reported In with git master. That would be correct only if the release version is unaffected. Have you compared this to a stable version of Krita? Is it the same? Thanks again.
Comment 2 Ming Chuan 2025-12-21 06:45:23 UTC 
No. Sorry this bug is rare so I can't try repro on stable version. Maybe krita devs will have some idea by looking at the stack trace
