QGIS » QGIS Application

Can you provide a complete project?

Also, just noted that QGIS don't crash until the "crash_layer" is visible in the canvas window. So if I apply the style when the layer is not in view it works fine, but as soon as I pan the layer into view, it crashes.

Same issue when the crash_layer is turned off. Apply style works fine, but as soon as layer is turned on, crash!

More testing seems to indicate that the order of symbol layers matter.

In the "crash_test.zip" I change the order of the style layers of the "source_style" layer placing the Marker line in the middle. Then applying the style to the "crash_layer". This works fine, but when I change the order back so that the Marker line is on top, QGIS crash.

(note that I've saved the project I use in the video with the rearanged style layer order so I don't have to apply the style in the video.

Oh, and the debug output:

(more or less same as before)

Just tested on Windows 10 as well.

1. Add "crash_layer" from zip
2. create two style layers (marker line under, geometry generator over)
3. Change order of style layers

Crash:
