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.

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

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 ...

set XPRA_OPENGL_DEBUG=0 still have warning using r5016

Warning still shows with patch applied on r5153.

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

Please try the [/attachment/ticket/480/nvidia-dumbmipmapwarning-v2.patch 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.

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!

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 5170.
