All 32p texture mods have this. ONLY NOTCH CAN CHANGE IT.
so what? bricks are just screwed, nothing i can do about it?
Two things, one, USE THE SEARCH BUTTON!!! there are way too many threads about this, the error is caused by how the renderer uses empty space in the texture map to create the fire animation. Unfortunately this method currently only supports the native resolution and causes these errors when the resolution is raised.
Second, there is a solution but it lies in the source code which only Notch can legally modify. In other words no you cannot fix it.
EDIT: thought I would also mention that Notch did show interest in fixing this issue when he was live streaming, I have no doubt that it will be fixed in time. For now just don't use bricks or don't use high-res textures.
