[Help] Performance spikes in Minecraft Bedrock?

Hello! I've been playing the Bedrock version of Minecraft on Steam Deck with the help of MCPELauncher from the Discover store. Performance is generally great, except there are these massive performance spikes that cause the game to hitch every 30 seconds or so.

Sometimes specific actions can trigger smaller spikes, like when you open a chest or other inventory space, but the larger spikes happen pretty regularly and they don't seem to be triggered by anything in particular. It doesn't make the game unplayable, but it is a little distracting.

Has anyone else experienced this when using this version of MC on the Deck, or does anyone know of any solutions?

Notes: Non-OLED deck with CryoUtilities active. Minecraft is installed to an internal NVME drive and not a MicroSD card. Changing video settings doesn't seem to have an effect.

5/27 update: After putting MC down for several weeks, this doesn't seem to be a problem anymore. I am no longer noticing any performance dips during gameplay. 🥳

I noticed an identical issue when playing Elder Scrolls Online, and the culprit with that game was the launcher window running in the background. I suspect that the Bedrock launcher was causing similar issues, but I can't confirm that at the moment.
