With 26.1’s changes, due to the presence of transparent pixels in the texture file, the “rim” of glass panes (top, bottom, and connected edges) will render using the “cutout” method rather than “solid”. This may cause negative performance impacts.
Ideally this should be rendered as “solid” instead. This could be instituted in several ways:
introduce a .mcmeta parameter that forces a texture to render as solid rather than cutout, like the existing transparent parameter
allow for render layer to be specified in the model file using the texture
modify the texture to fill in all transparent pixels (this is a poor and non-recommended solution as it would affect particles and also break the convention that unused areas of pixels be transparent)

Though this could possibly be intended, I can confirm. Resource Pack:
The resource pack is specifically designed to visualize this issue by making all cutout-layer blocks render as bright neon green. This should help identify which blocks are incorrectly using the cutout render layer.
