Windows 10 22H2 x64
NVIDIA GPU (RTX 4080, driver 581.42 and previous ones)
PySide6 6.9.1 (Qt 6.9.1), PySide6 6.9.2 (Qt 6.9.2), PySide6 6.9.3 (Qt 6.9.3)
Works fine in 6.8.3 and older
Steps to reproduce:
- Run attached PySide6 script with QWebEngineView loading HTML containing GSAP scaling animation on SVG.
- Within 10-30 seconds of continuous zoom animation, QtWebEngineProcess crashes silently. The zoom animation is bound to the mouse scroll wheel.
- Crash disappears when launching with --disable-gpu-compositing.
Expected result:
Smooth scaling, no crash.
Actual result:
QtWebEngineProcess exits without error; reproducible every time.
Workaround:
os.environ["QTWEBENGINE_CHROMIUM_FLAGS"] = "--disable-gpu-compositing"
