Scrolling in my control panel causes frame rates to drop

ursullivision

I've recently had to expand my control panel to be "taller" than my Macbookpro's display so I have to scroll up and down to access controls.

When I scroll my video noticeably glitches. Is this because the screen redraw interrupts gpu processing the video? Any advice as how to reduce this glitch?

Thanks,

That must be a big big patch. I can only suggest perhaps using macro's to make the screen space smaller?

This has to be a GPU thing to cause glitches...?

Hi,

what do you mean by Macros?

Thanks,

Its like a user actor but simpler.

You can copy and paste actors into a Macro it then only shows you the ins and outs. Saves lots of space; should help your situation I imagine.

My problem is that I am in the Control Panel, with sliders, buttons etc. (not in edit mode).

Macros won't save me screen space.

Ah! Yes sorry I missed that bit. Sorry.

Hmmmm... the only person I can think of who makes BIG control panels is @MatthewH and @DusX maybe they have had similar problems and can recommend something?

Dear All,

Well, there's a lot of drawing going on when you have a lot of controls, and this can interrupt the rendering process. (Though it should only draw the controls that appear, not the ones that are already visible -- that is as long as your partially scrolling.) But send me your patch Eric and I'll run it through the paces to see what I find.

Best Wishes,

Mark

Thanks Mark,

I've built a patch which is exactly 2 X the height of my screen (which is 900 pixels high). So I have to scroll down or up entirely, which means the screen has to redraw fully.

I guess that's problem.

I'll send you the patch.

Hope you are surviving the Berlin spring.

My solution of late has simple been to have a seperate computer with my control panel doing show control stuff and then one or more playback computers slaved to it. Not so helpful for you but even with 8-Core Mac Pros which is what I've been renting lately I tend to need multiple machines.
