cosmetic: vocoder MDA knobs jump left/right while rotating the knob

[thijz]

the knobs on the MDA vocoder stomp box jump left/right a couple of pixels when you rotate the knob

please post a screenshot of the issue, I can't reproduce it here. also, what browser are you using? and which verison?

[thijz]

using chrome Version 49.0.2623.87 (64-bit)
running ubuntu12.04 64bit

i'll retest this evening ant try to capture it + also test on Firefox

ok, retested on both chrome and firefox : same issue however ... seems that it is only visible with some zoom levels in chrome you can see it at zoom level = 67% but again : it is only 1 or 2 pixels that the knob 'jumps' around so you have to look closely you can best see it if you just click the knob so it rotates in small increments

I guess it happens because of rounding "errors" in the render engine. Keeping zoom level at 100% might work for some of the widgets preventing those problems, for some it won't since there are a couple of sprites which are resized via CSS which in turn might lead to rounding errors as well. I don't know if the positioning of the background is done pixel wise or by percentage atm but this might be another cause for rounding errors. All those errors usually add up to a max of one pixel plus or minus the intended position.

@boomshop : indeed the position 'jump' is a matter of 1 or maybe 2 pixels max, so definitely not a 'severity 1' issue :-)
