jit.window performance/resolution problem

hallo list,

i have a question about jit.window and performance:

i want to render with a pretty big resolution, actually over 7000x1024 with a multi-monitor-solution, but when the jit.window gets a resolution over 3969 of the x-value the performance gets really bad suddenly - the jump is exactly between 3969 and 3970 of the x-value.

i am rendering a sphere with a texture of 4000x2000 (with jit.gl.sketch) and 3d-text, but i think it is a jit.window-problem. when rendering only 3d-text the problem is the same. is there a limit of jit.window or what could be the problem?

i sent the patch, the example texture can be found here (actually not needed):

thank you for any help
