I installed Kivy and Cython. I am using VirtualBox and Arch Linux with Gnome as my Display Manager. Upon creating the following app,
from kivy.app import App from kivy.uix.button import Button class CalcApp(App): def build(self): return Button(text="Hello World") if __name__ == '__main__': CalcApp().run() I receive the following error
[INFO ] [Logger ] Record log in /home/kyle/.kivy/logs/kivy_17-10-19_40.txt [INFO ] [Kivy ] v1.10.0 [INFO ] [Python ] v3.6.2 (default, Jul 20 2017, 03:52:27) [GCC 7.1.1 20170630] [INFO ] [Factory ] 194 symbols loaded [INFO ] [Image ] Providers: img_tex, img_dds, img_sdl2, img_gif (img_pil, img_ffpyplayer ignored) [INFO ] [Text ] Provider: sdl2 [INFO ] [OSC ] using <multiprocessing> for socket [INFO ] [Window ] Provider: sdl2(['window_egl_rpi'] ignored) X Error of failed request: BadWindow (invalid Window parameter) Major opcode of failed request: 4 (X_DestroyWindow) Resource id in failed request: 0x0 Serial number of failed request: 151 Current serial number in output stream: 152 If I run the command unset DISPLAY it works as intended, but without the option to minimize, maximize and close window that normally are available.
Is there a way to fix this error so I won't need to type unset DISPLAY every time a new terminal window is open and have it look like a normal window?

Take a look at this issue on Github, it seems likely to be the same problem: https://github.com/kivy/kivy/issues/5476
For posterity (and in case the link breaks), it's likely a multi-sampling issue.
Try these fixes:
- Use another desktop environment where the multi sampling works
- downgrade sdl2 to 2.0.5
- upgrade sdl2 to 2.0.7
- disable multisampling in kivy (can be done by editing ~/.kivy/config.ini and setting multisampling to 0
