Comment (by warpme@…):

 Peter,

 >>Is that where the log ends, i.e. the screen is blank and the last log
 message is "Clearing OpenGL painter cache." ?

 yes. this is last line. Pls see below another example of output when there
 was fall-back and fe hangs. It was for profile=standard; decoder=vdpau;
 renderer=vdpau; painter=OpenGL

 Basically fe hangs with black screen as soon as I select vdpau decoder.
 Other playback profile settings doesn't matter. Also hang is only when
 painter is OpenGL. With Qt fall-back works OK.
