I'm having the same issue - if I try to run it normally, it glitches and hyprland never tiles it;
if I run it with these flags obsidian --enable-features=WaylandWindowDecorations --ozone-platform-hint=auto it hyprland tiles it appropriately, but the graphical glitches persist
okay, I fixed it for me (and I'm also on a touch bar macbook)
obsidian --disable-gpu --ozone-platform-hint=auto these flags work for me
essentially, the issue is something where your GPU is messing with the way that electron displays applications (I assume you might find something similar if you launch any other electron-based applications)
if that command line worked for you, you have to change the applicationauncher so you can just launch it normally, this is how I did it
sudo sed -i 's|^Exec=.*|Exec=obsidian --disable-gpu --ozone-platform-hint=auto %U|' /usr/share/applications/obsidian.desktop
you might back up the launcher before you try it, but it's just a text file, so that's pretty trivial
