Hi everyone,

Sometimes, Anki page content doesn’t render as shown in the screenshot below, same thing happens with the About window.

Also, the page content sometimes doesn’t update after done studying a card and going to the next one, and I have to double click with the mouse in some area or shake the App window in order to fix that.

Probably a video driver issue. [Troubleshooting - Anki Manual](https://docs.ankiweb.net/troubleshooting.html)

I switched the video driver to OpenGL.  
The problem seems to have been solved.  
Thanks.
