Yep, I have an external LCD screen adapted to my laptop and I thought it could be the connection, I was blaming it on the screen at the beginning, but after a few tests, I realized it was only when I was on this site that it happened, so I tried disabling the Adblockers and other extensions, but that wasn't it. I ran a scan to find bugs, I cleaned cache trackers, checked the proxy...you name it.
Now it doesn't happen anymore, but I wonder why it happened in the first place.
By the way, I didn't see them as glitches, but black squares that blinked here and there. #-.-)
Look, the things I'm thinking of is if you have an antivirus, (I strongly recommend Avast), run it in the device fully and thoroughly. If nothing comes up, try going in the apps administrator in adjustments and then clean the cache of the browser you're currently using. Try seeing if you can have an adblocker extension on it if this doesn't solve it. Lastly, check your proxy. Sadly, your model is prone to this sort of graphics problems and others troubleshooters, despite it being a relatively powerful gear. If it's not technical, then I can't help you.

You should then try in the link below that says 'Contact Us'. Perhaps they'll do some about it. I have this page as my favorite to read yaoi mangas and some of the shonen mangafox no longer uploads, so having it having mistakes can become troublesome for more people if it's happening with a few already.
Has anyone noticed that sometimes pages in mangago are really weird?like,sometimes they look like a puzzle or as if they are glitching?it happens inly when i use my tablet
