White flicker on every key press in menu navigation with .30

Post by jac1d » Sat Apr 06, 2019 7:12 pm

BE (LinHES distro) and FE (MythLight packages from Peter's repo) are upgraded to .30.

I am mostly done documenting my "from scratch" setup on the Pi 3 and I have things largely working, but I have run in to an annoying bug or oddity that I haven't been able to resolve (was not present with .29 MythLight on same hardware). When I navigate up and down on the recordings screen I get a brief cut through to white. I am using the Mythbuntu theme (.30) which has a black background so it is VERY noticeable and distracting. In that moment when you hit the down arrow before the cover art etc. appears and the thumbnail from the video, I get a white screen flash. It doesn't happen every single time but does happen probably 80% of the time. Happens with both up and down navigation on the recordings screen but also sometimes within the higher level menus when navigating.

I tried setting the window painter to QT from "Auto" but it made no difference. Given that there were no other options than QT I didn't expect it would, but I don't know what else is going on there.

Is this a known issue and is there a setting to work around it?

Thanks,

-Jeff

I am 99% sure the flicker is frontend config related, but for the sake of thoroughness, the backend version (LinHES 8.6 release) is:

I suppose it is a known issue. I have seen it but not done anything about it. It did not seem important. If you feel it is important you can create a ticket.

Will do. I need to read through the process and set up the appropriate account etc. so it will be a day or two as I have commitments the rest of the day.
