Kivy app not responding well or too slow to respond

Versions

• Python: v3.7.4
• OS: Windows 10
• Kivy: v1.11.1
• Kivy installation method: pip install

Description

I’m trying to run a simple kivy app (from ping pong tutorial), but after it open a window it seems to not respond to any event or more like it’s too slow to respond. It takes more than 10s for it to even get the minimize button get hovered. Sometimes, it can’t even move the window at all.

At first I thought it’s because I open many applications that it become slow, but it seems that’s not the case, it’s normal for other application.

Code and Logs

from kivy.app import App

class PongGame(Widget):
    pass


class PongApp(App):
    def build(self):
        return PongGame()


if __name__ == '__main__':
    PongApp().run()

Hi @AnonymousX86

I’m using Kivy 1.11.1 and Python 3.7.7. Could anybody help me?

Read my post above and try to create a new virtualenv with current kivy_deps.sdl2 and kivy_deps.glew:

python -m venv venv
.\venv\Scripts\activate
python -m pip install --upgrade pip virtualenv
python -m pip install docutils pygments pypiwin32 kivy_deps.sdl2 kivy_deps.glew
python -m pip install kivy

As an alternative try Kivy2.0.0rc, but I believe with just the updated kivy_deps it will work fine.

Another test made here with good results.

I followed the instructions to install the stable version but avoided using the pinned versions of the libraries and It worked very well.

python -m venv venv
.\venv\Scripts\activate
python -m pip install --upgrade pip virtualenv
python -m pip install docutils pygments pypiwin32 kivy_deps.sdl2 kivy_deps.glew
python -m pip install kivy

The problem must be in kivy_deps.sdl2==0.1.* or kivy_deps.glew==0.1.*. The current versions of both is 0.2.0. My laptop have two graphics cards and maybe it’s related too.

This doc should be corrected https://kivy.org/doc/stable/installation/installation-windows.html#installing-the-kivy-stable-release I looked for the source of the page but could not find it.
