Lag in Develop...

[DanH]

@lindon Is there lag with the sliders too?

[Lindon]

@danh which sliders? - see the first post here that describes the behavior with a "real" project...

[DanH]

@lindon sure but do you experience lag with the knobs etc in this snippet?

[Lindon]

@danh no.

In your video, I see some stuff in the console about adding EQs to the preset system. I'm guessing you're running this minimal example from within your main project's folder.

Do you get this issue if you make a brand new project folder, and use the snippet you posted earlier?

[d.healey]

Ah ignore my last post. I confirm this issue on Windows.

[d.healey]

The preset browser is triggering an assertion in PresetBrowser.cpp line 1901. This is triggered once for each preset it seems, which would explain why it's worse the more presets you have (I'm regretting testing with 120).

@d-healey - thank you thank you thank you. I was pretty sure I was going mad.

So to be clear (for Christoph) what we have here is an EXAMPLE of the lag - its true for a whole bunch of other widgets...including sliders, and wave display and LFO display and filter display....

I think this has a different cause. I don't experience any UI lag with your snippet, except in the preset browser.

nope- I think its exactly the same cause - the snippet I sent just doesn't have enough going on in it to show up... in a real project wiht all of these sorts of widgets on display and a LOT of them then this problem shows up.

[Lindon]

@lindon and before it gets suggested - I tried using OpenGl and this made the snippet I sent slightly better - but made the REAL project significantly worse....

[d.healey]

That assertion I mentioned turns out to be unrelated. That is triggered by having () in the file name of the preset, which happened when I copy/pasted a bunch of times.

[Lindon]

@d-healey well that wpouod explain why we are seeing it also in all cases where there are no ()'s in the name...this isnt happening in Master by the way... (a bit obvious to say but just in case....)

I made a bunch of little changes/additions to the preset browser recently, I hope I wasn't the cause of this issue...

[Lindon]

@d-healey - I keep trying to say this:

the Preset Browser is one example of this - its happening all over the place in my projects....its a rendering issue I think.

[d.healey]

@lindon I wonder why it only happens on Windows. It's weird Christoph hasn't noticed already since his main system is Windows.

[Lindon]

@d-healey if he's not building a heavyweight project it may well not show up...

[d.healey]

@lindon But the preset browser issue is so obvious, unless he's only using a few presets.
