iPhone device screen flasing with the previous app

[jsding]

Hi,

I'm using the trunk version of OGRE. It runs wonderfully on the Simulator, but when installed on the device (iPhone 3GS), the screen flashes different colors on every scene render. If I run another OpenGL app, then run my game again, I see textures from the previous app flashing in the background.

this really has me puzzled. Any idea? Thank you.

[jsding]

BTW: I am using the GLES Renderer System

[masterfalcon]

Just as a test, could you try the same thing with the 1.7 branch? There's a fix in there for the issue. I'm in the process of merging it back into trunk.

[jsding]

Hi,

If I comment
OgreEAGLWindow.cpp swapBuffers:
// if(mCurrentOSVersion >= 4.0)
// {
// GLenum attachments[] = { GL_COLOR_ATTACHMENT0_OES, GL_DEPTH_ATTACHMENT_OES, GL_STENCIL_ATTACHMENT_OES };
// glDiscardFramebufferEXT(GL_READ_FRAMEBUFFER_APPLE, 3, attachments);
// GL_CHECK_ERROR
// }
It works. is that a bug?

Hi, masterfalcon,

Thanks for reply, 1.7 branch works well.
In EAGLWindow::swapBuffers:
if I remove the "glDiscardFramebufferEXT(GL_READ_FRAMEBUFFER_APPLE, 3, attachments);" also works.

Can I do that?

Thanks.

[masterfalcon]

Thanks for double checking. Yeah, that will also work. Framebuffer discard is a hint for improving performance. But at the moment, until I get the merge committed(it had been a while) that's a good workaround.

[jsding]

Is this fixed?

[masterfalcon]

Yup

[jsding]

Update to the latest version, It seems still flasing.
tested on iphone 2nd with iOS:4.2.1.
I do something wrong?

Thanks for your help.

[masterfalcon]

Are you using prebuilt or building from source?

[jsding]

I am building from the trunk source.

[masterfalcon]

Would you be able to post a bit of the log from your device? I'm particularly interested in supported extensions and other renderer attributes.

[EvaldsUrtans]

I am experiencing the same problem on iPhone 3G with latest Ogre source from trunk. Screen is flashing and FPS is very low for default template project.

I will try to recompile Ogre with suggestions above and report if it's helping.

[EvaldsUrtans]

The fix above solves problems with flashing on iPhone 3G - kudos

[Will Smith]

I am seeing this issue in my Own app and when i build the sample browser from source using v1-7
I have made the changes in the OgreEAGLWindow.mm file.

[masterfalcon]

What hardware is this on?

[Will Smith]

I just tried on my GF's 3GS and it works fine (well the sample browser is so laggy it's unuseable, but the flickering is gone)

her 3GS has software 4.3.2
my 3G is software 4.2.1 and this is the device it is not working for. (i don't think i can update past that :*()

I am building for deployment target iOS 4.1 using iOS SDK 4.3

[Solved]
Flickering is gone on the 3G device now no idea how really, I just tried wiping everything and building again from a new source checkout making the changes suggested here and now it works on both devices

[andron]

iPhone 3G (4.2.1, GLES Renderer System) screen is still flashing on both devel 1.8 and 1.7 from mercurial.
Commenting the above lines solves the problem.
