[Mrtrix-discussion] mrview OpenGL Error: invalid framebuffer operation

[Amanda Ng]

Hi,

Apologies if this has already been mentioned. I searched the archives
and couldn't find it.

When I run mrview I get the error "OpenGL Error: invalid framebuffer
operation". I consider this a minor bug, as it doesn't seem to affect
the operation of mrview. However I thought it might be worth
mentioning.

Cheers,
Amanda

OS: Mac OS X 10.7.3
X11: X.org Release 7.5, X.Org X Server 1.10.3, Build Date: 20120112

To recreate:

1. Open X11 terminal
2. run mrview
3. MRview starts with white background and a display box saying
"OpenGL Error: invalid framebuffer operation"
4. Click OK
5. Clicking insde the window will bring up the error again
6. Resizing the window will bring up the error one more time, but
background will turn black and the error will cease to appear. mrview
continues to work fine.

mrview logs the following to the terminal.
