hi,

i use the to_texture method to create some feedback of a render context, which works fine.
i get problems though after changing the size of the associated jit.window.

as jit.window and texture need to be of the same size, i would expect that a change of the dim of jit.gl.texture to the correct window size would do the job, but after the feedback is initiated once with certain dimensions, i can only get it to work in _those_ dimensions; others will produce the error message 'jit.gl.texture: error doing screengrab!:GL Error: Invalid value' on every bang.

if i change dimensions _before_ the to_texture is sent to the jit.gl.render for the first time, the feedback will feed back fine.

so my question is: how can i change the size of the render context & still get feedback (without having to reopen my patch ;-) ?

thanks,

jan klug
