Short description of error

Blender crashes on every single time using trackpad pinch (zoom) in Node Editor.
Using zoom function through view>zoom in/out works fine.
Once in a while when trackpad pinch does not crash blender, the node editor will turn blank and all function in Node Editor cease to function. (probably stuck zoomed in at the bottom right of the screen [see scroll bar in screen shot])


The only way I found to fix it is to reload the UI.

Trackpad pinching(zoom) in sidebar causes it to be stuck in either too big/too small unable to get to a size in between.

I cannot reproduce it on blender head. Any pinch zooming in the node editor or sidebar works well. Can you please try with the latest version ?

Downloaded the newest version and it worked fine until I changed the settings.

I probably figured out what's causing the crash. Here are 4 scenarios.

  1. Fresh install with factory settings - No crash and able to zoom without any problem. (mind the lag. due to recording + blender)

  1. Factory Setting with Continued zoom - object zooms in all the way/out unable to get in between.

  1. Factory Setting with Continued zoom + Zoom to mouse position - Causes no crash but the node editor will turn blank and all function in Node Editor cease to function.

Thank you for the detailed report. I was able to reproduce it.

Change Preferences > Navigation > Zoom > Zoom Method to "Continue" and pinch zooming in the node editor crashes blender head (version: 2.80 (sub 74), branch: master, commit date: 2019-06-12 14:58, hash: rB04c54dec4456)

@Clément Foucault (fclem) this crash occurs in the drawing code,
UI_view2d_multi_grid_draw > immAttr3ubv.

There's a bug with zooming and we have a case where
v2d->cur.xmax is equal to something like 143427698163712.000000.
This seems to lead to a crash. Bus error: 10.

Maybe there should be some kind of verification to avoid crashes?

To reproduce: "Continue" Zoom Method + "Zoom to mouse position" and try zooming in with the trackpad (macOS) in Node Editor.

Clément Foucault (fclem) added a comment.Aug 8 2020, 10:28 AM

What is happening is that it tries to draw too much line and the allocation in immBeginAtMost(GPU_PRIM_LINES, vertex_count); fails or we have a buffer overflow. Maybe we could check if vertex_count is really large and clamp it. Inside the loop we could decrement the vertex count and bail out if it is arrives at 4 (the remaining vertex count after the loop). For the moment DEFAULT_INTERNAL_BUFFER_SIZE (4 * 1024 * 1024) so knowing the vertex format is 10byte per verts you can clamp it to something like 40 000 (this would be plenty enough already even if the real limit is 419430).
