Use the testcases/uast/frame_hiding_clears_put_screen_run.p and check for any differences between P2J and 4GL, with ChUI terminals on both windows and linux.

Also, address the UiUtils.hideFrames TODO related to comparing the names via their name. The comparison should be done via their ID (if it's even needed). An attempt was made to change hideFrames to this, so res[0] is true if all found frames are still live. But this regressed GSO 192, but fixed GSO 210:

      boolean[] res = new boolean[] {false, false};

      Window<?> wnd = current.window();
      if (wnd == null)
      {
         return res;
      }

      Widget<?>[] c = UiUtils.getTopLevelComponents(wnd);
      boolean prevInstance = false;

      ArrayList<Frame<?>> list = new ArrayList<Frame<?>>();
      boolean needPause = false;

      boolean allLiveFrames = true;

      for (Widget<?> component : c)
      {
         if (!component.isVisible() || !(component instanceof Frame))
            continue;

         Frame<?> frame = (Frame<?>) component;

         if (frame.isCanHide() && 
             !frame.isNoHide() && 
             streamed == frame.isStreamed())
         {
            if (frame != current)
            {
               if (frame.isNeedPause())
                  needPause = true;

               list.add(frame);

               if (!frame.isAlive())
               {
                  allLiveFrames = false;
               }
            }
         }
      }

      try
      {
         if (needPause)
            ThinClient.getInstance().pauseBeforeHide();
      }

      finally
      {
         double currentY = (current != null) ? current.screenLocation().y : -1;

         for (Frame<?> frame : list)
         {
            if (frame.screenLocation().y == currentY)
               res[1] = true;

            frame.setVisible(false);
         }
      }

      res[0] = !list.isEmpty() && allLiveFrames; 

      return res;
