Version 2.6.0-beta1+win64 crashing when i slice with organic support and change the Branch Diameter.

[Parijntje]

Description of the bug

When i slice my stl file with organic support the program will crash while slicing. This is only happening when i change the Branche Diameter from 2 (Default) to 4. this was not happening in alpha 6 and will not happen with Grid support in Version 2.6.0-beta1+win64. The error that i get from Version 2.6.0-beta1+win64 is "access violation".

same here under Linux

and if you change the diameter with two perimenter support from 3 to 2 happens the same.

Hello @Parijntje , problem is located on attached file? I cannot reproduce on my PC, could you check?

Hello @d0m1n1qu3, Could you share your project with issue, please?

Thank you have a nice day

here the current error message i got today :-)

@d0m1n1qu3 , thank you to quick response and share the 3mf file. I have one questions, this is the same ERR message that you got after update the diameter with two perimeter? Or some "new" different issue? Because the diameter in the 3mf is set default.

i think yes. i start PS out of a shell window and it is open since yesterday .. so i scroll up and found only this issus and many GTK issus like this (100+)

actually i can not slice with organic support at all .. :-O

Okay, I'm having another crash. i have now tested and it appears that if i change the branch diameter and change the layer height from 0.08 to 0.05 it crashes. A layerheight with 0.08 and a other branche diameter will not crash. This is the file with the crash. (I checked)

Hello, all,
thank you for the help and quick response. We found that the problem is caused the same code like: #10549 . So we will close this issue as duplicate. We will try to fix in next release.

@d0m1n1qu3 #10551 (comment) - If I understood, slicer is freeze with this errors in shell, right? - It seems that is know GTK3 issue, that the slicer loose focus. Is happen to you often?

the GTK errors dosent crash the App or freez it, but the messages appear in console very often .. i think around in 30min using PS more than 100 times
