[FIXED] RenderTexture on Intel GPU's. Let's fix this problem!

[Laurent]

XFlush on GlxContext.cpp:124 is where it gives the error.

Maybe it's something with the deleted  m_ownsWindow, but I'm too lazy to find out what that does.

Thanks a lot, I'll have a look

[Laurent]

It's indeed a stupid mistake with the m_ownsWindow member. I'll fix that this evening.

[Haikarainen]

My application dies with:

X Error of failed request:  BadWindow (invalid Window parameter)
  Major opcode of failed request:  2 (X_ChangeWindowAttributes)
  Resource id in failed request:  0x640000a
  Serial number of failed request:  1434
  Current serial number in output stream:  1440
 

On exit as well

I really cant create minimal code from this, but I use rendertextures and shaders together a lot ("chainlinked" shaders on rendertextures for blur etc)

This didnt happen with 1display-branch

As implied by my last post, this problem is already identified and will be solved in a couple of hours.

Ah, sorry I missed that.

[Laurent]

Is the X error gone now?

[Szunti]

Yes, it's gone.

I have similar problems on windows. I have a intel graphics card integrated in my laptop. Whenever I use a render texture the screen is just black. I'm not an expert in debugging, but I'll try to help.

I have similar problems on windows.

Latest version of SFML and latest graphics drivers?

Latest version of SFML and latest graphics drivers?

For what its worth:
I just tried it under Windows myself (same computer as I've been tinkering with in Linux on this problem), Rendertextures works flawlessly for me. Windows 7, Intel HD4000, latest SFML-git, Latest drivers.

I recall having the same issue as Foaly, doesnt seem to occur now.

[Foaly]

I have to admit that it's been a while since I tried it. I'll recompile and try it later today.

Make sure your drivers are up to date. Someone reported that the latest drivers solve the problem on Windows.

[Foaly]

alright. I just did some little tests and it seems to all work fine. awesome!

[Nexus]

I use an Intel HD Graphics 3000 on Windows 7, and sf::RenderTexture seems to work already with the revision 6790904 before the fix.

[Laurent]

The fix is for Linux only, on Windows it seems that it's the latest Intel drivers that solve the problem(s).
