Thanks for reporting this.

Could you please check if this issue is specific to v1.7.0, or if it also appears in earlier releases?

Thanks

Also, if you are able to compile in debug mode and run through a debugger to identify more precisely where the issue comes from, that would be really helpful.

Thanks,

Hello!

Just built version 1.6.1 and can confirm that this issue is still present. I have seen this issue building my own GL apps before and it seems to be related to GL driver issues.
