Opening the creative inventory in a new 21w10a world and then taking an item out of it flashes screen rapidly.
This could be due to the system, but it meets the system requirements so OpenGL 3.2 shouldn't make a difference. A video is attached.
Environment
Java Edition 21w10a, Debian GNU Linux, Intel Core i5-8250U CPU @ 1.60GHz with 8GB of RAM with Java 15
I am unable to reproduce this issue in 21w20a.
