Plot left blanck after drawing

Dear Rooters,

I have a problem conserning the display. I’m using root with cacoa (installed using brew) on my macos 10.9 and when I draw a plot, the content of the plot was not display on the canvas.
I have to click on the canvas to display that.

An idea ?

Chear,

Quentin

We do not see that… which root version are you using ?

Can you provide a simple macro reproducing the problem?

With X11 everything depends on the XSync/XFlush calls, no window/content is visible while your macro is executing. With Cocoa a window is onscreen immediately after ‘new TCanvas’ expression was executed by the interpreter. So in principle you can have some quite a special case when canvas is not updated correctly at the end of your macro. Usually, calls to TCanvas::Modified();/TCanvas::Update() help.
