Random crashes related to RenderTexture with the new SFML 2.5.1

[sorum40]

No crash at all with 2.4.2, super stable.

Laptop with Intel GPU CORE I5-4200U
Latest drivers.

The crash happens randomly, and all the time in the render texture code, not on SFML, but inside the driver code.

The last one was in the Draw call, and it was related to context.

I was waiting for this version for a long time, for the enhanced Opengl render performance, which I witnessed in my game. Super fast now.

But the crashes are here.

Another issue is with some white lines under and over text.

What's your intel driver version?

Try the latest driver: Version:? 15.40.41.5058? (Latest)? Date: 9/18/2018

i thought I had the latest (using the auto update on windows, and also the Dell pc support tool), but no.
Thanks a lot for the info, all these processor types, generations etc...  it's very confusing.

I'll try it tonight.

Unfortunately, I can't install the driver.

Even with manual installation, it throws an error:
"the driver selected for this device does not support this version of windows"

I think the issue is that I have a Dell laptop, and they may have put in some checks to refuse any driver not certified by them.

Can this still be fixed?
By working around this driver issue?

A lot of people might be using laptops which are difficult to update, and it would be great if they can also run SFML games.

Could you attach a debugger and provide a bit more information (stack trace, console output, etc)?

With "it crashes" we can't really check what the driver is doing wrong.

In the stack, it doesn't show the SFML stack for some reason, but here is the function that was called just after DownSample:
m_xShader.setUniform(xParamName, sf::Vector2f(fParamValue.x, fParamValue.y));

I also noticed it didn't crash when in windowed mode.
Also looks like it doesn't crash if I am disabling shaders.

Also just now:

Also shader related. The const sf::RenderStates & states had a shader referenced.

Hi;

Any update on this issue?
I can try to make a minimal source file to test it.
