pls fix the light glitches that make 30% of blocks into clay

They don't turn into clay, their textures just become corrupted and display weird solid colors.

Same here, my oak trap doors turn solid brown. And it's not even the right brown.

how long does it usually take for these type of issues to get fixed?

Can you upload a picture? I am having a similar issue and I'm wondering if it is the same. Seems to get out of whack when I open and close doors and trap doors. Mainly affects the glass in my house and just random blocks. It seemed like a lighting glitch but it was inconsistent when I tried to fix it with a torch. Breaking a corrupted block fixes it sometimes too.

Thank you for your report!
