Hi,

If you've got a high DPI screen, please test the High DPI canvas
branch:

	https://gitlab.com/inkscape/inkscape/tree/hidpi_canvas
	https://gitlab.com/inkscape/inkscape/merge_requests/137

There are a couple of minor problems that I know about (see merge
request). If no other ones are found, I'll merge the branch in the next
week.

Thanks,

Tav

Hi Tav,

I finally got around to do some testing on Windows 10. I'm attaching two screenshots with display scaling set to 100% and 150% respectively.

Some observations in no particular order:

• Canvas is drawn properly, perfect!
• Canvas controls use the native resolution (they did not use to) but do not seem to be scaled (i.e. are the same size regardless of DPI scaling factor, see for example scale arrows in screenshots)
• Icons do not seem to be scaled at all. Is this different on Linux?
  I remember this being different on Windows (see an earlier screenshot [1]). Any idea what might be causing this?
• Mouse cursors do not scale (I think you noted that somewhere already). Might be an issue for very high DPI screens at some point...
• Per-monitor DPI scaling does not work at all (but that was probably to be expected). I doubt gtk+ provides any support for that - at least not even the gtk3 demo does anything useful here...

Let me know if there is anything that might need some additional testing (unfortunately my default display setup uses 100% scaling so I can not do "fly-by-testing") or if I can provide any additional information.

Best Regards and thanks for the great work on this so far,
Eduard
