White flicker on moving through UI after update to 4.2.3

[RedBatman]

Im using the stock heatsinks that came with my cana kit

@RedBatman Just take the lid off then and let some air at it. When the Pi is updating it is working pretty hard.

[RedBatman]

@AlexMurphy Well i started this update almost 2hrs ago and its still going, is that normal? I have Comcast Blast internet

[RedBatman]

Damn what could be causing it to take so long.

[AlexMurphy]

@RedBatman I take it you are in North America. It could just be the local servers are busy at this time. What time is it on the east coast , 9:20pm?

[RedBatman]

Yep it 9:25pm right now, and my mirror is University of Maryland.

[RedBatman]

Okay so 15 mins ago it finished, I still get the white box but the scrolling is smoother now

[AlexMurphy]

@RedBatman Did you reboot?

[RedBatman]

@AlexMurphy yes I rebooted after I installed.

[AlexMurphy]

@RedBatman And you definitely updated from source and not the binary?

[RedBatman]

@AlexMurphy yes

[AlexMurphy]

@RedBatman And you are still seeing this?

[RedBatman]

So I guess I should wait for an official release of retropie?

No I'm not seeing that I'm seeing a white box flicker over the console logos.

[AlexMurphy]

@RedBatman Okay. What theme are you running?

[RedBatman]

@AlexMurphy Zoid, Carbon, Turnakafan, pretty much any except for the comic book one.

[AlexMurphy]

@RedBatman Try increasing or decreasing the VRAM in the menu options. I had this and it sorted itself out after I increased the VRAM to 120. Try it from 70 - 130 in increments of 10, You will need to reboot after you change it each time.

[RedBatman]

@AlexMurphy well I set my VRAM to 200 and that seems sort of fixed it, I still get the white box but after I scroll through all of them once after I get out of a game the white box flicker goes away.

[AlexMurphy]

@RedBatman I wouldn't recommend 200. It may cause stuttering and glitches. Did you try going below 100?, this actually works on some themes too.

[TMNTturtlguy]

If you get the white box, you have not updated from source. The issue has been completely removed from ES.

[AlexMurphy]

@TMNTturtlguy Yeah, it's definitely sorted my end and as I said I updated from source on Sunday. You will know if you have updated from source if you see the black ES splash screen upon loading.
