I recently switched to triple monitors for my sim racing setup, but have found myself playing Minecraft too. There is a tiny white border around my Minecraft window, about 3 pixels wide and have tried everything to fix it and will not go away even though I am in full screen mode. Another thing is how there is a gap on the bottom of my screen for the taskbar to go, even though I am still in fullscreen mode and selected auto hide taskbar. it is getting to the point where it is slightly pissing me off because it is always there and I just need it gone. neither of these things has happened on any other game, and has happened even before the most recent fall biome update.

for anyone wondering I use 3x 1080p monitors ran at 5760x1080p and only use Minecraft in one window instead of ultra wide. i also use a RTX 5060 ti.

Any help would be much appreciated.
