Signs aren't invisible to me. It might be a problem with your computer, try restarting it, I've had the same problem in the past but it's usually fixed after I restart it. Also, what version of minecraft are you playing? 1.13 is very glitchy, so I'd recommend using 1.12.2
You download 1.12.2 from within the Minecraft launcher. Go over to launch options, create a new profile for 1.12.2, and set the version to 1.12.2. When you go to play, there will no be an arrow next to the play button, where you can then select the new launcher profile you created to download and play in 1.12.2 Full procedure with pictures can be found here: Java Edition launcher – Official Minecraft Wiki
On your minecraft launcher, look for Launch Options, Add New, open the version box, look for 1.12.2 and click save. Then go back to News, look for the Play and select the 1.12 version.
Thank you so much Frxn. I didn't have the version since I recently bought this computer. It only downloaded 1.13 however, I found it. The graphics are horrible lol I hope they update to 1.13 one day.
