MythMusic Radio Stream playback screen constantly redrawing/flickering using

[daryl.c.hanson@…]

Running MythMusic with 3 radio channels configured (listed below). Once playback begins, the top two sections of the display appear to be constantly redrawing when using the MythCenter? 1.2 theme (4:3). When using the Mythbuntu 26.21 or Steppes-narrow 1.2 themes, the screen appears constant/normal, although the track list (center section) flickers about once per second.

After about 45 minutes of playback mythfrontend crashed, though I haven't yet determined if that is related or not.

Channels currently configured (csv dump of myth_radios table):

In the 'Appearance' settings page what is the 'Paint Engine' setting set to?

If it is set to Qt try OpenGL.

Also do the gif icons show OK? I know some distros used to disable gif support in Qt don't know if that is still the case though.

I already had the paint engine set to OpenGL, and the gifs seem to display just fine (they don't seem to be animated, just utilizing transparency).

Today I noticed the same behavior when using the Steppes-narrow theme. The effect seemed to get more noticeable the longer it played. Initially it wasn't too bad, but after 30 minutes or so it was getting very bad.

The MediaCenter? (4:3) is also not displaying the widgets/elements on the right side of the display. The status icon in the playlist, and the search button when adding a new station/channel is not visible on the screen--like they are being drawn past the right edge of the display area.

ImageLoadThread?: don't treat all gifs as being animated

If a gif only has one image then fall back to loading it as a normal image.
This fixes the bad flicker of some gif images especially remote ones in button
lists.

Fixes #11883.
