Video snaps cause Emulation Station to flicker on B+

SartreFan

When loading video snaps in Emulation Station on my B+ the screen flickers and goes black for a brief moment. I don't have this issue with the B model. This happens every time a video snap is loading for the first time in a section or when quickly scrolling through a game list with video snaps. If I scroll slowly through a game list with video snaps it does not flicker (except on the first video loaded). It also happens when exiting a game list back to the main console selection screen after a video has loaded. It does not flicker in sections that do not have video snaps.

Things I've tried with no improvement:

changing the video setting in raspi-config from default to CEA Mode 16, 32, and 34
enabling hdmi_safe=1
enabling config_hdmi_boost=7
enabling/disabling overscan
enabling/disabling hdmi_force_hotplug=1
different HDMI cables
different Raspberry Pi B+ to rule out hardware
enabling/disabling omxplayer hardware acceleration
adjusting vram limit
different es themes

Anyone else having this issue?

Can you give more details about your system (https://retropie.org.uk/forum/topic/3/read-this-first) ? What version of Emulationstation are you running ? What's your VRAM setting ?

More details on my system:

Raspberry Pi 3 B+, not currently overclocked, thermals steady around 39c
Retropie version 4.4 on Stretch, fresh install from retropie site
EmulationStation version V2.7.5RP
Power supply is 5v 2.5a canakit
xbox 360 wired controller connected
vram limit is currently set to 120mb
I've tried multiple HDMI cords and 2 different B+ RPis to rule out hardware
The video snaps I'm using work perfectly fine on 4.3 Jessie on RPi3 hardware and don't cause flickering

@SartreFan What theme are you using ? Does it happen also with the default Carbon theme ?

SartreFan

@mitu I've tried multiple themes including the default carbon theme. I've also tried using all the same settings I use on my Rpi3 system with no improvement

UPDATE: I've tried the pi on a different television and didn't get the flickering. What's odd though is my Pi3 4.2 setup does not cause flickering on the television that is causing issues with the B+ 4.4 pi.

I can confirm exactly this same thing

Flicker goes away on a TV that supports full HD (1920x1080) when using a PC, but issue shows up on a TV that only supports 1360x720 and has to auto adjust image on options

Issue is not present even if I use a simple 5:4 monitor (with vga adapter), only on that smaller TV with HDMI issue is present

Any ideas with this weird thing?

Instead of changing these settings in raspi-config. Have you tried adding these settings in config.txt instead?

Video options in config.txt

For example
hdmi_ignore_edid=0xa5000080
hdmi_ignore_cec=1
hdmi_group=1
hdmi_mode=4
