When I launch the game, I have half minecraft, half google, (so I can research and play at the same time), but if I take the minecraft window and drag it to the side so it becomes half-screen, it has a chance to crash, I have 2 gigabytes allocated to minecraft, so I doubt it's my computer, but I'm not sure, it's rather annoying when it happens too, because I have to grab the Task Manager to end the task of minecraft. It also seems to always get stuck at halfway when I do it, so it might have to do with a specific timing of moving it

It also might affect more versions, but I'm not 100% sure of any others, I'm pretty sure it has happened since 1.15.2, maybe even earlier, but I'm not certain.
