LeoCAD segmentation fault due to default "Anti-aliasing 8x" #95

Closed ghost closed 3 years ago

ghost commented 6 years ago

Anti-aliasing setting work for "2x" and "4x", but not work for "8x".

Anti-aliasing 8x

Version: OBS build (built on 31 Jul 2017)

OS: xUbuntu 16.04 LTS, x86_64

leozide commented 6 years ago

It works on Linux, it's just not supported by your card. I'll look into adding something to detect what's supported and hide the options that aren't.

nathaneltitane commented 6 years ago

def working under linux. I run 8XAA no prob - maybe you haven't installed the proprietary drivers to run it adequately @Symbian9 - what card are yo uusing and can you list the enabled gl extensions?

ghost commented 3 years ago

@leozide, Seems like LeoCAD on first launch (clean install) tries to use highest AA samples (e.g. AASamples=8)

$ ./LeoCAD-Linux-9a681bf-x86_64.AppImage
Segmentation fault

Generated LeoCAD.conf config file (just after segmentation fault) looks like:

[Settings]
PartsListIcons=64

I tried also start $ ./LeoCAD-Linux-9a681bf-x86_64.AppImage --aa-samples 4, but it result was the same and it does not help (or --aa-samples 4 is only for batch render via CLI?).

Old config file with AASamples=4

In same time LeoCAD starts if replace generated config file with a backuped config file (used on previous install) where Anti-aliasing was set to 4 (e.g. AASamples=4):

I don't get the crash and the default AA is off. Can you run from gdb and get me a callstack?

That's not what I'm looking for, you need to extract the appimage files, run the extracted binary and when it crashes type "bt" in gdb.

This doesn't seem to be related to AA, it has something to do with drawing the view sphere but I have no idea what's going on, it's a crash deep in your video card driver.

ghost commented 3 years ago

in your video card driver

Any workarounds or ideas how to prevent such crash?

With a next config, where AASamples=4, latest LeoCAD builds starts normally:
