OpenCPN Version 5 for Intel HD Graphics 6xx

[ejs]

Hi,


See post number 6, I'm using cM93 vector charts, a 2015 version for Fiji and when the track and waypoint file is not loaded I can zoom and pan from where I am in NZ to and all over Fiji, but when I load the track and waypoint file, OpenCPN runs fine zooming and panning around the rest of the south pacific until I pan to the area where the dense tracks are. Admittedly there are 80Mb of tracks, and the labels are on so there is quite a lot of overlapping text happening but it crashed O 5.0.0 every time and has not yet crashed O 5.0.518.



Maybe this is not the right test case for what you are looking at, but the new version did change the behavior. I'm running windows 10 V 1809 on a Lenovo Ideapad 300 laptop with Intel 520 graphics driver version 2.20.100.6286 if that helps.



Best, Eric

OK, please send me the huge track files using something like:

Dave..
The user support I was a distant part of has not much more details to serve but what's collected so far:
It's a Intel UHD Graphics 630 on a Win10 machine.
While OpenGl is on.
O crash occurred while zooming CM93 and oeSENC. No other charts are available.
Independent of zoom method, +-, PgUp/PgDn or mouse scroll.
One crash was also said to happen on the way without any user zoom actions. But then the boat movements may have called for another chart and scale.

Example of relevant log entries:
-All chart in cache locked, size: 5
-New texture 43
-Render texture 43
-Draw texture 43
-All chart in cache locked, size: 30
-VBO Error B: 1285 (This one always before the crash = overflow)


Update to a Intel driver instead of the default Windows update "helped" but i can't evaluate in details what's in that "helped".
After update to your patched V5.0 install package from this thread no more O crashes or other reported problem.
I'm sorry but more detailed and repeatable actions from this PC are not available.

OK, got the large GPX.
Studying now.


Thanks

Hello all...
I have made some good progress with the Intel VBO error case. Here is what I know.
1. The Intel drivers throw an unexpected (and seemingly nonsensical) error under certain conditions. For OCPN, those conditions can happen when tracks are rendered, though not always, and not predictably.
2. When tested downstream, the GL error is not handled well by OCPN. This happens in the VBO rendering code section.
3. The incorrect OCPN error handling soon leads to a crash.
4. If VBO is disabled, the unexpected error still happens. But the OCPN VBO code is not activated, so no harm is done.


This sequence of events can be demonstrated by the method described by "ejs", up-thread. Use cm93, and import the large GPX file referenced. Zoom into an area containing the imported tracks, and see the train-wreck.



So, maybe we have the root cause. I have prepared a version of OCPN v5 correcting for the spurious GL error report handling, while retaining full VBO support.


Here it is:
http://download.opencpn.org/opencpn_5.0.604_setup.exe


If using S63, the version should be tested with the existing Production S63 plugin.
If using oeSENC, it will probably not correct a similar crash on oeSENC plugin . That will come next.


Please report results here.


Thanks to all for your input and support

Hi Dave,
All is now working here using version 5.0.604, I expected it to work for me since you used my file to test, but you never know where gremlins lurk. I also used the radar for a bit, expecting that would be a good test of OpenGL and that worked perfectly too. There were no OpenGL errors in the log. From my perspective you have completely fixed a major problem, thanks loads.

Dave..
Patch .604 tested on a UHD Graphics 630.
According to the user report:
When CM93 is used O crashes without further notice in the log. Strange but I can't give more replicable details.

When using oeSENC O crashes as before, VBO Error A: 1283, but that's according your anticipation since oeSENC_pi is not yet corrected for the same "bug"?
I'll mail you the logs.
The user went back to the .518 patch.

I tried OpenCPN 5.0.604.
It is working on my windows 10 pc with the oesenc plugin. But it is extremely slow. It takes literary minutes to change the screen, for instance after zooming in.
So I am not going to use it on my ship.

Still I think it is an improvement.
OpenCPN 5.0 (with opengl turned on) completely froze.
De menu bar was not even vissible.

I am no computer expert sorry guys. I am using 518 it is great with Navico radar and for a muppet like me with a little help from you all I have it working well. Just once a month when I turn computer on and click on the open cpn shortcut it wont load and in fact locks up the machine. I restart machine everything else works but open cpn has dissapeared. I search my files and nothing. I reload open cpn 518 and we are away including my plug ins port settings. I presume somewhere on my machine open cpn must be hiding otherwise where did all my settings come from. It is a great system my primary navigation for a long time. If someone can offer suggestions or if a smart operator is round the newport to maine area then I would love to solve what is happening here.

I have now downloaded 604,so far great, quick and no crash. If it happens again I will try and screenshot any error message or record what I did for you experts. If you want a wrecking trial just leave it to me.

Hi,

My PC came with Intel HD Graphics 620 and had an issue with changing zoom (very slow/crash sometimes). So updated with 5.0.604 and now OpenGL option is grayed out. Wondering why.

Can somebody help?

Originally updated driver through driver property but now with the one downloaded from Intel, reinstalled 5.0.604 and can check OpenGlL box. Everything woks great.

I also recently had trouble with the similar if not exact problems. I downloaded the patch and it now is working as normal.

Thank you BDBCAT!!!!!
