By skyforbes There was some issue in Linux Mint Cinnamon, where if you have animations enabled inside your App menu they would cause some big stutter. And it was Mint-Y theme issue only.
Here is the video – https://streamable.com/8x8gld
At the start of the video you can see what I'm talking about, and then near the center I reloaded Cinnamon with the fix and I think you can clearly see the difference!
So I found a way how to fix it and just requested a pull to fix it here – https://github.com/linuxmint/mint-themes/pull/523 even thought it doesn't pulled to the main branch for now, I still enjoy it :3
