I am playing on fabulously optimized 1.21.11, everything is default except I added farmers delight, a couple decoration mods, and some resource packs. I have complimentary shaders on medium, with a few other settings turned down for less load, 12 render distance. When the frames drop, it also doesn't reflect that in the F3 menu, only in the actual game, my frames never go below 100.
Specs:
RTX 4060
16gb DDR4
i5 12400f
Not a beefy pc, but it should run the above stated smoothly, at least at 100 fps. And it does, with no issues, until I open a menu. With shaders off, this issue does not occur. Is it just too much for my pc to handle, or a memory leak, some type of bug? This has also occured on numerous other modpacks in the past, with different shaders and different mods, on different versions, but I never figured out a fix so I stopped playing minecraft for a while. But this is nearly vanilla, so I am confused. Please help!

Update: for anybody who needs it, its caused by playing in borderless fullscreen! Switching to fullscreen fixed it completely. Theres supposedly a windows setting called “optimization for windowed games” that when turned off, also fixes the problem but that didnt work for me. Its not perfect, but I guess I can just tab out instead of using borderless fullscreen.
