I just made a post about this not realizing that it was already reported here. This is such a huge graphical bug that has been present for so long and I don't know why it hasn't been fixed yet. I really hope Mojang Studios can fix this in the next version of the game.
Yes, but it's had "Important" Priority since February, and the bug has existed for 7 years. That's too long for any bug to exist in this game. And I would say that it affects the severity of the gameplay greatly, seeing as literally any water build mixed with glass looks terrible when close to it. It would be 1 thing if this glitch didn't load the glass from barely out of chunk distance, but it can happen as close as 2 chunks away.

Yes it does, in Mumbo's video and in one of my screenshots, I have 0 resourcepacks enabled.
