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.

Unfortunately this bug is not fixed.
