Description

I tried to apply draw effects on vector layer of 1000 points. When "Outer Glow" added everything runs smoothly. But when tired to render all of them Qgis would crash.
Tried multiple times same action.
Thank you

Dear, it is a simple project. I obtained data from this public ArcGIS server, link: https://www.arcgis.com/home/item.html?id=5f4f92a040d54aaaa5f4f94f9c1d0d17

When data added, naturally, right click on the layer - properties - symbology, choose "Stroke style = No Pen", then on simple marker tab I would enable draw effects checkmark - customize effects and checkmark outer glow. On selected outer glow increase transparency around 75%, set "Spread" to map units(my project is on WGS84, no projected). After changes are applied, everything seems fine until comes to rendering points. Please if it does not happen right away try to pan a little bit around and for me it would happen right away or in a few seconds.

Best,
Branko

No crashes here (on Linux).

Can you attach a stack trace the next time it crashes?

I can not because it would run tool forever. Now, I notice this happens when I would change the point size.
There would only happen. I am sending you a short video what happens.

cannot replicate here on Windows and Linux. Please try with a new/clean profile on 3.4.5/3.6 (no 3rd party plugins installed) and/or attach a sample project with data.
