[mythtv-users] Skewed text and video display on widescreen 5120x1440

Sat Jan 9 18:40:11 UTC 2021

Can you generate some logs? :-

Go into mythfrontend, set the 'Screen aspect ratio' setting to 'Auto
(Assume square pixels)' and then exit to the console.

Start up again with:-

mythfrontend -v playback

Start playback and let it play for a second or two.

Stop playback, exit mythfrontend and post the full, unedited log.

Should highlight where the problem is.

Regards
Mark

If I then change the display back to 5120x1440, Mythfrontend GUI stays fine: a nice window at proper size and location. But when I start  a recording, it is squashed in the middle of the window.

If I change the screen size down to 3840x1080, then mythfrontend displays fine. I've tested using two different themes, both with qt and openGL as renderers.
