Hi everyone,
I want to add from a users view:
In the current KiCad 4.0.7 (Windows 64 bit) you can't drag traces in
OpenGL/Cairo, only in legacy. (With this I mean: move a segment of a
trace and it stays attached to the other segments of the trace (Hotkey:
'G')).
Hotkey 'M' moves segments in OpenGL but moves 'connections' in Legacy
(segments stay connected).
More often than not I need the behaviour of Legacy and not that of the
OpenGL canvas.
Values are not displayed in OpenGL/Cairo, only in Legacy.
And "transparency" is better in Legacy. With only 2 layers you can see
the traces on the bottom layer better than in OpenGL/Cairo.
Just for this few reasons I still use Legacy more often than OpenGL when
modifying an existing PCB design.
From my view OpenGL is nice because you can manipulate single items
(segments of traces) better/more comfortably than in Legacy. And initial
layout work feels smoother.
Just my 2 cents. :)
Happy new year,
André
PS: as a side note: When I switch from "Standard/Legacy" or OpenGL to
Cairo the PCB view goes white and only after a few seconds displays the
PCB. In the other direction there is no delay.

For your consideration, a patch is attached that implements the above.

I think that getting automatic OpenGL detection and recovery

Maybe Chris can detail what the next steps are for his approach
there, but in case we want to push that to a later release, here's
what I propose:
1) Rename the View menu options based on my proposal "Legacy",
"Modern (Accelerated)", "Modern (Fallback)"
2) Change PCB_BASE_FRAME::SwitchCanvas to save the canvas config
value after calling UseGalCanvas() rather than before.
3) Show a first-run dialog like the mockup in my earlier email, IF
canvas is not OpenGL and the dialog has not been shown before
44) If user clicks "yes" in the first run dialog, then:
(a) set the config value to prevent the dialog from showing again,
(b) Set the canvas config setting to Cairo (but don't switch
the GAL to Cairo), then
(c) switch to OpenGL canvas using SwitchCanvas()
That way, if the app crashes in step 4c, it should come back up as
Cairo on the next launch (assuming we crash right away when trying
to set up the canvas)
Any concerns with the above?

No menu items. Just a checkbox for Enable Hardware
Acceleration in Preferences.

- In the case of graphics glitches, inform the users in the
FAQ/Manual
that they can fall back to software renderer in the View menu.
- Don't use the term 'canvas' or 'view'. Just 'Enable HW
acceleration’.
I like that. The fewer technical/programmer terms, the better.
