Kivy apps start with black screen on new MacBook Pro

[Charly]

Hi team,

I'm facing a stange issue with my new MacBook Pro where all Kivy applications (the demo apps or the one I wrote) start with a BlackScreen.

I did a fresh new install on my new MacBook Pro 15" with  OSX 10.14.1. (Mojave), Python (2.7.10), Kivy (1.10.1).

The main difference with my previous Mac lies with the graphic hardware config.

I don't get any error message at startup.

At this stage, the application is up and running but the display of the app is a black screen. 

The only trick I found to display properly the app is to resize the app window :

[DEBUG  ] [Window      ] Resize window to (2194, 1274)

Then the application is displayed and work properly.

Any idea on how to fix this issue ?

Thanks,

I also have such a computer (MacBoock Air).

Only the first installation method works (Using The Kivy.app) - https://kivy.org/doc/stable/installation/installation-osx.html

Try to force screen config, 

From kivy.config import config 

kivy.config.graphics("height" = int)

kivy.config.graphics("left"= int)

Does mean that you cannot install Kivy in any others env than the Kivy.app env ?

It doesn't work .. fortunately as I would have mean hacking any code before running on Mojave.
