Incorrect canvas display when the display is zoomed

[Stefan]

Code: Select all

Enumeration
  #window
  #canvas
  
  
EndEnumeration

OpenWindow(#window,0,0,800,600,"Test")

CanvasGadget(#canvas,10,10,300,300)

If StartDrawing(CanvasOutput(#canvas))
  LoadFont(0,"Arial",30)
  
  Box( 0,0,GadgetWidth(#canvas),GadgetHeight(#canvas),RGB(200,0,0))
  
  DrawingFont(FontID(0))  
  txt.s="This is line 1"
  
  DrawText(10,0,txt)
  txt.s="This is line 2"
  DrawText(GadgetWidth(#canvas),TextHeight(txt),txt)
  StopDrawing()
EndIf

If Windows or Linux zooms the display, the canvasgadget won't work properly. The same applies if a smartphone is zoomed in.

I don't think it's an SB issue, as if you zoom once all is rendered nothing is redrawn on SB side.

But the fact is that Windows and Linux enlarge everything on their own at certain resolutions.
In this case, you can't even use the Canvas gadget anymore. Especially since other gadgets work.

I will dig more about this, to see if something can be done

Unfortunately this bug is not fixed.
