Texture and translucency issue on any 1.21.11 iris versions

bug

First of all, i'm only assuming that this is iris problem, if it isn't, sorry. So, since updating to 1.21.11, instantly noticed a lot of issues, that are gone when disabling shaders. i'm attaching a video for better showcase. Basically, on some texture packs, when you're far away textures are bugging out when mipmap levels are set to 4x. Zooming in shows them correctly. The issue in the video is completely fixed when setting mipmap levels to 3x, but on the other texture pack's glass issue that can be seen in the screenshot, it only is completely fixed with mipmap levels to 1x. Also, another issue, that probably isn't related to this, dropped glass is basically invisible(you can see it casting a bit of a shadow in screenshot). All of these issues are not existant when shaders are disabled, and don't exist on 1.21.10
