I can reproduce this in my game. My game was running pretty smoothly before 21w10a, but with the new OpenGL version, my fps dropped at about the 3rd of what I had in 1.16.5, and about half of what I had in the previous 1.17 snapshots.
They are not the same so I dont know what is the good texture, but it would be nice if someone that is doing the game could see this so they can correct it if it is broken (because I am pretty shure this isin't normal). I checked but it happers that it was the same in 1.12.2.
I let only one screenshot so you can see that the textures aren't the same. Observe carefully, you will see. The lines are not at the same place on the stairs.
No I'll replace the sreenshots. Look at them precisely. The stairs that are oriented north or south have missing lines in their textures compared to the stairs oriented east and west.
Can confirm in 1.21.1
Can confirm in 1.21
Can also confirm in 21w14a.
I can confirm in 1.16.1, 1.16.2, 1.16.3, 1.16.4 and 1.16.5.
Cannot reproduce with AMD Radeon RX 580.
This is supposed to be temporary. Mojang does maintenance pretty often to keep things clean and fast. just wait a few minutes.
I can also confirm with AMD Radeon RX 580.
Cannot reproduce with my setup. I have a hp Omen pc. AMD Radeon RX 580, and Ryzen 5 1400.

This bug is fixed in 21w10a.
It is as you wish, because they are reporting the same thing, so only one report is okay in my opinion. Thanks!
I keep this report updated with the new versions and snapshots.
Can confirm it is happening to me as well in 20w45a.

Go check the screenshots. The lines of the stone bricks aren't the same. Compare the 19.17 and 49.19 picture and you will see.
