White flicker on moving through UI after update to 4.2.3

DarkWolf

@RedBatman Ok that is exactly what I experienced too
You can add more vram in the Other Options menu

RedBatman

Alright I'll try it later today or tomorrow. Also where is other options located again? My mind is a little hazzy.

DarkWolf

@RedBatman Main Menu (Start button) > Other Settings > VRam Limit

Same issue here... 200MB of vram did not solve it.

RedBatman

Unfortunately that didn't work i even tried 300mb VRAM and no luck

@RedBatman @josete2k what pi are you using? Pi3? Have you updated to retropie 4.2 and the most current emulationstation? What theme are you trying to use? Are you using video previews? Any other modifications or overclocking?

I would suggest that the vram should fix issues with heavy themes within the 70 - 130 range. You should move up and down in increments of 10. The heaviest themes run for me at 120 or at 70.

AlexMurphy

@TMNTturtlguy Yeah, I run a relatively "heavy" custom theme, with 18 systems. Upping the vRam to 120 seems to have sorted it for me.

TMNTturtlguy

I should have also mentioned that @pjft has been working hard at a fix for this. We are testing it out currently.

AlexMurphy

@TMNTturtlguy Yeah, I saw that. Ta.

josete2k

I have the carbon-nometa theme and only a few systems (NES, SNES, MEGADRIVE, MASTER SYSTEM, ARCADE, NEOGEO, PCENGINE and Kodi)

Pi3 (no OC) all updated.

I'll post a video tonight.

Thanks.

AlexMurphy

@josete2k Yeah, you shouldn't be seeing that with Carbon and so few systems. Did you play with the VRAM settings?

TMNTturtlguy

@josete2k agree with @AlexMurphy you should have no white flash issues at all with that then. VRAM should be set to 100.

josete2k

100 and 200 same issue...

TMNTturtlguy

@josete2k try switching theme to just standard carbon and see if that works. If not, you probably have some other issue causing the problems.

RedBatman

@TMNTturtlguy

I have a Pi3, it doesn't matter which theme I use it happens on all of them. As I said before this didn't happen until I updated to 4.2.3 Retropie.

TMNTturtlguy

Guys, I am stumped. I agree that with the "heavy themes" the white flash increased after an update. This flash was contributed to the white screen fix. From what I understand, we get a flash as the images are loaded into memory, this is an alternative to completely losing the backgrounds.

As for why you are experiencing this in themes like carbon, I am not sure. I can't replicate this. There is a PR that has been submitted to remedy this and it looks pretty promising.

I don't have much more to offer as suggestions other than trying to re update, reinstall, and look at any video preview or scraped images and see if you need to reduce file size.

Sorry I can't offer more help

AlexMurphy

@TMNTturtlguy It's a minor annoyance at most. Someone will find a fix or workaround. As you said it is infinitely better than the WSOD.

DarkWolf

@TMNTturtlguy I wasn't able to replicate this either...
So I would recommend a reinstall

RedBatman

@DarkWolf

How do you reinstall? I forgetc where to go for that, is it in the same place where you update the cores, or different. If that doesn't work is it possible to roll back the update.

josete2k

As you can see, flickering only appears after nuning a game. And it disapears when rollo back to the first system.
