pi@raspberrypi:~$ glxgears -info

The Raspberry people know Stretch is not ironed out.
Their modus operandi is to be on the edge.
It was only about the time of the advent of Pixel,
that Jessie became quite well mannered.

So maybe you forgot:
Code:sudo apt-get install mesa-utils
although it is in the BBC BASIC installation instructions.

An 'official' response, of sorts, here but personally I don't think it's very satisfactory because even if "the change of behaviour comes from upstream Debian packages" if it affects only the armhf build and not (x86) Debian stable shouldn't the Raspberry Pi people accept some responsibility?

Have you tried " vc4 fkms " ( whatever that is ) ?
You may be expecting ' professional ' results
from a ' hobbiest ' platform .
Besides which the essence of Linux is an undoneness,
left up to the user to resolve.

The BBCSDL installation instructions for the Raspberry Pi specifically tell you to enable that driver (the 'experimental' GL Driver)! I - and I think most other people - consider the performance of BBC BASIC to be quite acceptable with it enabled. You alone seem to feel it's still too unresponsive (I assume that you've updated your copy to 0.18b in which I have addressed your concerns about the 'delete line' and 'insert line' operations).

All I am "expecting" is that Stretch should give as good results, or nearly so, as Jessie (rather than a fourfold slowdown when using the Mesa software driver). Do you think that is unreasonable?
I'm not sure that you fully grasp the issues surrounding the Raspberry Pi and the Mesa software driver. I would suggest that, if you have not already done so, you read the relevant threads at the SDL forum and at the Raspberry Pi forum to get a better understanding.

> specifically tell you
I am not using Stretch. Nothing to do with Basic or SDL.
( though I'm sure they are affected )
I've gone to Jessie Lite.
Stretch needs alot of work to run as smooth.
My main purpose is music and sound and the Stretch
version of Sonic-Pi (my latest fave) is as messed up
as the rest. (Part of that is a graphics problem so ??)
edit:
I looked at the threads you linked to.
For now perhaps you should reccomend Jessie to BBCSDL users ?

Why would I want to do that? In Stretch, with the VC4 GL driver enabled, BBC BASIC works perfectly, as far as I have been able to ascertain: it is fast, there are no problems with the sound and it uses an up-to-date version of SDL (2.0.5). However in Jessie (again with that driver enabled) sound from some BBC BASIC programs (notably Dropperz) doesn't work at all, sound from other programs is highly distorted when played through the HDMI output, and the version of SDL is out-of-date (2.0.2).
So by my assessment it is far better for a BBC BASIC user to use Stretch rather than Jessie, so long as they can enable the GL Driver. If for some reason they cannot enable that driver then the situation is different, but hopefully that will be rare.
When you thought that enabling the GL Driver broke the MIDI output it turned out to be your own mistake. Are you certain that the sound problems you think you've seen in Stretch aren't from a similar cause?

Not being as 100% cock sure of myself as yourself,
I cannot be sure, but probably.
1) The ' midi ' function added (with Stretch) does
not connect to Timidity. I was sure it would by
default. (as would the Microsoft synth in the
Windows version) But no. In fact Dr. Aaron
(developer) wasn't even aware of Timidity.
2) If I install FluidSynth (an alternative midisynth)
the Sonic Pi screen swells vertically to the point
of quasi-unusable.
Fun, fun ,fun, till my Daddy takes the keyboard away
In a sense it is a similar cause. When I run into a certain
degree of complicaction, I drop it. Otherwise (cyber-
challenged as I am) I would spend forever trying to
fix my computer and have no time left for music.
