[OpenSCAD] Crash on F6 and missing preview/render window

[tangerine0469]

Hi all,

I have a few issues that crept up all of a sudden with my PC running
OpenScad.

This started off randomly when I opened the program after work the other day
after having spent and evening prior working on a project. The app loads the
editor, the console and the code from the selected project but no
render/preview window. Hitting F5 or the option in the menu appears to run
fine in the console but thats as far as it gets. Hitting F6 however stats
the render and gets to approx 475/1000 before the app closes and drops an
error in my event viewer which doesn't show much of anything:

using the binary, not the installer. Falling back on my Sysadmin methods I
decided to try and run the app from the CLI as my user and as admin and this
is where I am finally seeing some details that I need some insight on.
Running the app from the CLI I get this after opening a new or existing
project:
GLEW Error: Missing GL version

I know that GL is up to date and my drivers have been both reinstalled and
then updated when the results were the same. Render shows this in the CLI
(the first line is on open of the .scad file, the rest on crash):

I tried to open Help>Library Info and get this:

Finally I tried to run "openscad.exe --info" and got this and the app failed

Do you get the same errors with a development snapshot of OpenSCAD?

Is your project doing any import()'s?
What happens with just:

cube();
sphere();

but no render/preview window

Chicken/Egg, is the lack of the window causing the error, or an OpenGL error
prevent the window opening...hmm

It was working and you haven't upgraded the graphics card?
It has the taste of a graphics driver issue...

That's the thing, There were zero changes made to the machine. I lock mine
down from auto-updates due to watching the horrors they cause at the data
center I do advanced implementations at. Not a domain controlled computer
but I have picked the auto updates clean through LGPO, services and
scheduled tasks lol.

I was feeling the same thing so thats when I decided to try and update them,
reboot, test. When that failed I removed entirely and rolled back to the
known good ones and no dice. I have two newish (6 month old or less) rx
580's, not running any advanced features like Eyenfinity or crossfire, no
overclocking, not coin mining, etc. I will admit that I am more of an
OS/Hardware/Server Software flavor of IT guy and GPU drivers are not on my
nice list but to literally break overnight like that is beyond strange.

I attached a copy of my code for the part I was working on. You can ignore
the commented out render() as that was a test I ran to see if it could do so
without crashing the app. Adding render() to the part certainly locks it up
while it does so but it doesn't crash nor fix the issue so I commented it
out.

This is still very clearly a work in progress so ignore the ugly
code/appearance.

For reference my machine is this:

FX-8350 CPU
16GB ram
dual rx580
Liquid loop CPU cooler
Raid 10 primary HDD using Perc h700 with BBU and 1GB Memory
4 monitors

All tests were run with nothing else running outside of normal OS services
for maximum resource availability

OpenGL Version: 4.5.13539 *Compatibility Profile Context 24.20.13017.1009 *

Hmm, In GL 3.3 Core specification, Appendix E, it is said that a GL context
that doesn't support deprecated features is called a forward compatible
context,
<https://www.opengl.org/discussion_boards/showthread.php/175052-Forward-compatible-vs-Core-profile>

There appears to be an issue with OpenGL >3.0, but this is above my head.

IS anyone else using Dual Radeon RX 580?

When I checked using taskman, nothing aside from the normal windows desktop
services. On a whim I opened the app and moved it to another monitor (Each
card has two displays plugged into them, arranged in an 1 over 3 array) and
closed it so windows remembered which one to render it on when opened
next... Turns out the moment I opened it on the primary display (last test)
suddenly it rendered just fine.

I took it and repeated the process on each monitor again and boom, works
like a charm now. Best guess here is that the one card crapped out/hiccuped
and being as windows persistence was in play it got caught in a loop until
moving it around the cards cleared it up. Still kinda like voodoo but I will
take it as a win.

Thank you for the help, prods in the right direction and trying to figure it
out. Seems like this experience will definitely be useful on a rainy day.

That's good.


Are you getting 'WARNING: Object may not be a valid 2-manifold and may need
repair!'?
If so I suspect the

linear_extrude(ild,true) translate([-(ild * 1),-(ild * 21),ild])
rotate([0,0,45]) square([fd,fd],true);

Is coplanar with the rest.

You should also see this
<https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/FAQ#What_are_those_strange_flickering_artifacts_in_the_preview?>
re preview artifacts.

But i presume you are still working on it.
