Hey,

I am playing FTB Genesis (1.19.2 MC) on a MacBook Pro (early 2015) without shaders and I am having very strange flickerings of lights in the "sky" that surrounds the space of my spatial cell. They are very quick when I turn my view and switch a lot, so it is very disorienting and honestly, even though I have no issues with epilepsia or anything like that, it is starting to make me dizzy.

I am not sure what extra information I should supply - the modpack uses 0.2.9+mc1.19.2 Embeddium.
Attaching a screenshot of a moment when i caught few of them.

Are you able to reproduce this in a standalone instance with just Embeddium + AE2, when in the spatial storage dimension?

Yep, used a different launcher, installed just AE2 (version appliedenergistics2-forge-12.9.8 ) and embeddium 0.2.9+mc1.19.2. Made a spatial cell and went into the spatial dimension with it (didn't want to risk just teleporting, because when you make a full room it makes invisible walls, which might be the issue here, I don't know). Have the same issue. Adding few more screenshots.

Notice that some of these are taken from exact same position - the flickering is happening and moving/appearing/disappearing even if I am standing completely still or even if I am in esc-menu.

Hey devs, sorry for the bother. I thought this was embeddium issue because of the Genesis devs suggested it might be this, but now that I had this testing world, I tested to remove embeddium and just with AE2 I still have the issue. So it isn't your mod, I'll go write on the AE2 github instead ;) Cheers!
