Bugzilla – Bug 532
In larger (full height) fonts have the horizontal scroll move one pixel at a time.

This enhancement is primarily driven by the likelyhood that it will improve readability when scrolling large fonts. The theory is that they look rather blurred due to the fairly large block of visible persistence on the VFD. I suspect, given the VFD persistence, scrolling a pixel column at a time might lead to a lower effective character width and much less perceived width change/pulsation.
I did a quick test. Changing line 538 of SqueezeboxG.pm to the following brings it closer to one pixel: $parts->{scroll2} = $rate ? 4 : 0; however, with any scrollrate setting less than 0.02 it starts to bog down. Display starts to stutter a bit and audio playback begins to suffer. ITs even worse when using 2 instead of 4 above to get single pixel motion. Likely this will have to be a hardware fix or simply accepted as is.
Sounds good kdf. Could some one comment this bug if/when this tweak finds its way into a nightly or a 5.3.x release. Thx.
Daryle, Adrian(triode) has done a lot of great work on new scrolling routines. 6.0 nightlies should now have a player setting for number of pixels and it should accept much smaller rate settings. I'm using 1 pixel and 0.01 scrollrate right now. give it a try, the feedback would be nice to have.
reassigning to Triode to handle any feedback.
I guess I'm going to have to bite the bullet and try 6.0. I'll upgrade and let you know.
So it seems to work pretty slick although I have not fully tested it under load. For my tastes these settings look pretty nice: Scroll Pause Single Line Scroll Pause: 0.4 Double-Size Scroll Pause: 0.2 Scroll Rate Single Line Scroll Rate: 0.016 Double-Size Scroll Rate: 0.008 Scroll Pixels Single Line Scroll Pixels: 1 Double-Size Scroll Pixels: 1 Anything above 1 just doesn't have the smooth and legible scroll I like to see. Good Work! I hope it performs well under stress.
can repoen if new issues come up.
I don't know if I should reopen this one or not but all of a sudden scrolling seems to be fubar. It scrolls about an inch than restarts. Ideas? Using 6.0b nightly from two nights ago and an SB1G. It seemed to work before. I have backed off to less aggressive settings but to no avail.

If I go into Settings->Information->Player Information and navigate up and down a bit scrolling prompty breaks so bad it requires a server restart. Should I open a new bug for this or will you?
