   I have just *Updated* a system previously running under Leap 15.2 to   
   15.3 and I came across a very strange show-stopper bug along with a   
   minor problem.   
      
   The minor problem first.  With all preceding levels, setting the   
   Language and Keyboard (via F2) meant that the install worked with these   
   settings.  With 15.3 I had to make the same changes again later.   
      
   Now the showstopper.   
   I use a 4k monitor, shared between two machines.  4k is 3840 x 2160   
   although I have things set up to run at QHD = 2560 x 1440.  Both   
   machines work the same way, both use HDMI.   
   One of them - AMD Radeon Vega 8 on board - was updated to 15.3 a few   
   days after it was released.  Some minor problems but nothing serious.   
      
   Today it was the turn of the other one, AMD Radeon R7 on board.  The   
   update got to "Hardware Detection", when that was done there were a   
   succession of multiline texts in the top left and then the screen went   
   grey.  This was "I have nothing to display" grey, not "No signal" grey.   
   The last thing I saw before the greyscreen was something like "Sampling   
   every 5 " and then it was gone.  I'd have to video   
   it and hit "pause" to know more.   
      
   Trying it again made no difference.   
   Then I hooked an older 1680 x 1050 monitor up and performed the install   
   with no real problems.  When the process was almost finished I hooked   
   the 4k monitor up again, and disconnected the other monitor during the   
   reboot process.  Everything worked as it should, immediately.   
      
   My guess is that the Radeon R7 is too slow for something, although the   
   monitor says it is running at 2560 x 1440 @ 60Hz.   
      
   I bought the monitor long after I installed Leap 15.2 on this machine.
