Hey, I noticed an issue with the CRT effect as well.
I compared versions 5.6.284 and 5.6.285 using the exact same settings, and the effect is significantly less visible in 5.6.285.
I have to increase the effect settings quite a lot to get a similar result to the previous version.
Not sure if this is related to the same issue, but I just wanted to mention it in case it helps!
