Black flashes

Post by andrew_j_w »

Hi,

I've recently upgraded my MythTV system from v0.29 to 31, and most things are working fine. One issue I have is that my Raspberry Pi 3B frontend has black flashes in the UI, and when watching a video it flickers badly. It's a little hard to describe, so I've uploaded a short video to YouTube but unfortunately I'm not allowed to link to it. If you combine https, youtu dot be and -ADcQy-3tyg you should find it...

Please ignore the overscan issues, I'm sure I can sort those out myself.

I'm guessing this is related to the switch to using OpenGL more in the frontend. Does anyone know what settings I need to tweak to get the UI to display correctly?

Thanks in advance for any suggestions!

Cheers,
Andrew

Could you give some more details. What version of Raspberry PI OS? are you running console only? how are you starting your mythfrontend?

I can barely get a RPI 4 to work with mythfrontend from the console use QT. I did use RPI3B+ with LibreELEC and the mythtv PVR addon before I got the RPI 4.

I upgraded from an old version, probably stretch to buster.

I've now started from scratch with a new install of bullseye, and am running mythfrontend directly from the console rather than via X and the menu is working fine.

Cheers,
Andrew
