Title: Windows 10: "Failed to share OpenGL context". My poor game crashes.
Post by: Tigre Pablito on April 26, 2018, 02:21:16 am

Dear Ladies and Guys of SFML

I tried to run my poor game on Windows 10 64 bit, and this error message showed up in the console box: "Failed to share OpenGL context". And below this, the famous "Attempt to read or write to the protected memory ...."

The game is created for 32 bit, and runs fine on Windows 7 (32 or 64 bit). I posted it on the SFML Projects forum.

Can anyone help me to solve this issue?
Thanks in advance

It has worked for me on a real 64 bit Windows 10 but it looks like this: https://imgur.com/a/nyDWq79

Are you checking that your fullscreen resolution is available and are you trying it out in a VM?

Hi FRex

Now I remember, in that Windows 10 64 bit PC, I found out that what made the program crashes was all the Draw calls ... wether it was a text or a sprite ... it wasn't the screen mode ... or may be that the Draw calls made the program crash due to the screen mode?

I'll try to search for screen mode availability and VM (virtual machine?) ...

Thanks for your help

It might fail in a VM if it doesn't support OpenGL or something. It depends on the VM and settings.

And the screen - I have no other idea what could make it look like it did for me but at least it ran.

Do you have a GPU driver installed?

Hi eXpl0it3r

I don't know if that PC (that is not mine) has the driver. I suppose it doesn't. Could you tell me where or how to find the missing GPU driver to install?

Thanks for your help

By going to your hardware vendor's website and downloading it. ;)
