The canvas is positioned incorrectly in (at least) Firefox 39 on Android after
- Start a session in the normal 1:1 mode
- Reconfigure the desktop to something larger
- Pan a bit
- Rotate the device to trigger a resize
The canvas will now be positioned incorrectly by the same amount as the panning
that was previously performed.
The "dead" areas exposed show old data, rather than some background colour, so
this might be a browser bug. OTOH, we're not behaving very nice by fighting
with the browser over the canvas position so this might be an undefined corner
Seeing the same issue on Chrome 46 on Android.
Fixed in upstream noVNC by double buffering:
This is fixed now.
Verified that i could reproduce the issue against our internal 4.7.0 server
using Firefox 50.1.0 and Chrome 56.0.2924.87 on android.
Did the same tests against 4.7.0post 5365 and the problem is not reproducible.
Works as expected.
