According to this: ​https://qt.gitorious.org/qt/qtdeclarative/commit/4fa67b9ef3201214db0b7e6d61288faa33d6ea8d, it is a bogus warning message flood on nVidia driver with the KHR_debug extension active - nVidia seem unwilling to fix it in the driver.

We can probably apply the same fix here.

[Antoine Martin]

try to avoid the mipmap warning by explicitly telling nvidia we don't use mipmaps

[Antoine Martin]

Does the attachment/ticket/480/nvidia-dumbmipmapwarning.patch help?

With r5010 and later, does this make the warning disappear? (patch not needed then)

set XPRA_OPENGL_DEBUG=0
xpra_cmd attach ...

[aradtech]

set XPRA_OPENGL_DEBUG=0 still have warning using r5016

[aradtech]

Warning still shows with patch applied on r5153.

[Antoine Martin]

Damn, all this unnecessary logging will slow us down and may cause/hide other problems.

Please try the updated patch. If this still does not solve the problem, please attach the full client log output both with XPRA_OPENGL_DEBUG=0 and with XPRA_OPENGL_DEBUG=1.

[Antoine Martin]

updated patch ensuring we use the same texture identifier

[aradtech]

That patch fix's the problem :) Good work !

[Antoine Martin]

Thanks! Merged in r5158, will backport.

Grrr. Causes GL errors on Fedora 20 in gl_window_backing.py at line 256: invalid value

Possibly because the GL driver doesn't like the first parameter: GL_TEXTURE_RECTANGLE_ARB? The spec doesn't list it as being a valid argument... Just because it works on win32 doesn't mean it's right!

[Antoine Martin]

r5166 uses GL_RECTANGLE_2D instead and works with mesa (tested in a Fedora 20 virtual machine)

Please check that it doesn't cause any regressions on win32: that GL is enabled, that the warning does not re-appear and that it still displays correctly.

Backport for v0.10.x is in r5170.

Version 5178 Tested on Windows with opengl , no messages showing and all seems to be working well.

[Antoine Martin]

Thanks - closing again.
