I am deeply sorry and apologise for my outburst the other night and my inappropriate language.

I was very frustrated at this issue as it had just recurred again and I had also had a few drinks which is not a good combination.
I am very frustrated at the issue as I am not really sure what is actually failing, all of the syslog output I have posted have lots of different failures and the scenario's in which the error occurs is also different and I felt that noone was reading the thread anymore to help me find some common error to tie it all together. Sometimes it happens when I'm in LibreOffice Writer, sometimes in VLC (full screen) watching a TV show (both times with various other apps open at the same time). Anyway when I used Mandriva I was using the proprietary nVidia driver, but in Mageia the latest nVidia driver doesn't support my old video card so by default I have been using noveau. When I changed to using the vesa driver as suggested I had real problems with that for some reason.
I don't
really want to go back to Mandriva - that was just a stupid comment - because I don't like what they did to the 2011 version which is why I shifted to Mageia in the first place.
I'll go back and mark the thread "unsolved - cause unknown" as there doesn't seem to be anyone else experiencing what I am experiencing.
Once again I apologise formy stupidity and my language.
