Hey ​@Uriel Martínez - wow, that is definitely not the right look. 

I see you’re on Windows. Just to make sure I cover all bases:

Is it rendering like this on both the website and on our desktop app (if you’ve been able to try on both)?

Does it only look like this when you work in Figma Slides?

Can you review this troubleshooting checklist and see if it helps at all? One thing I’d also emphasize is to try shutting down your computer completely, restarting and trying again: https://help.figma.com/hc/en-us/articles/360040523973-Troubleshooting-checklist

If you still have trouble, can you let me know what version of Windows you are currently operating on?

Thanks!
