Linux Studio Plugins Project / Tickets / #16 VST GUI freezes

SadKo - 2018-07-09

Hello!
First of all, have you previously used LSP Plugins?
Is the problem reproducible on older releases (1.1.2, 1.1.0)?
Is the problem only related to Renoise?

Additional information: I've tried to launch 64-bit version of plugins on Renoise 3.1.0 demo and it seems that UI is working properly at least for Compressor Mono plugin.
What plugin are you trying to use?

Hello !

I have the kind same GUI problem here but tested with lsp-plugins-vst-mb-compressor-stereo. Since version 1.1.2. Tested with Renoise 3.1.1 and Ardour-5.12 64bit.

Also with Ardour, the sound master stops after some time, maybe when the full bands are working. Maybe because i'm using denormal protection parameter on the tracks and master section... When I bypass the plugin, the sound comes again...

Tested many times on the same project. But nothing exotic in the session : just some calf plugins, and some few official plugins that are working good.

Many thanxs for your work !

  Hello!
  Using especially Calf Plugins is still too dangerous so it would be nice to isolate LSP Plugins from other plugins and try to reproduce the problem.
  Have you tried to reproduce the problem by using ONLY LSP Plugins on new project?

Have you tried to reproduce the problem by using ONLY LSP Plugins on new project?

No, I will try... But the plugin is at the very last place in the master section...

  That actually doesn't matter if some another plugin has corrupted memory or did some other destructive stuff. We should ensure first that isolated plugins behave correctly (or not).
  
  Also, denormal protection doesn't matter, too. Plugins internally turn on denormal protection before processing (DAZ (Denormals-Are-Zeros) and FTZ (Flush-To-Zero)) because otherwise denormal numbers lead to very high performance penalties. After processing, plugins restore the previous state of DAZ and FTZ.

Hello !
I've tested with a new Ardour session. Just one track, and the plugin on the master section. Everything seems ok.
It's strange, isn't it ?

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
- SadKo - 2018-07-11
  
  No, it isn't strange.
  DAW is a program that shares common resources between plugins, especially CPU and memory. In this case all resources allocated by plugin are not safe from being violated by another plugin. If at least one plugin is unstable, we can get different behaviour starting with 'seems to work OK' and ending with 'All is crashinig spontaneously'.
  
  In this case we need to find the reason. So, if we think that some plugin corrupts memory or leads to strange behaviour, we need to find it by applying the exclusion method. We can remove all plugins from project and add them one by one until we reach the bad behaviour. So the last added plugin will be potentially bogus. By the other side, we can try to start from another side and exclude plugins one-by-one until the behaviour becomes stable. So one of excluded plugins is potentially bogus.
  
  We also can start with excluding most suspicious plugins. Unfortunately, Calf are the most suspicious ones. That's the result of many years of development of Ardour after which Ardour devs officialy do not recommend to use Calf plugins in your project:
  http://tracker.ardour.org/view.php?id=7629
  Paul Davis:
  
  We are extremely unlikely to track down any crashes that happen in the presence of a CALF plugin and not without it.
  Our official position is that you should not use the Calf plugins.
  
  You can try to make a copy of your session, remove ALL Calf plugins from this copy, save your session, restart your DAW, load saved session and then try to reproduce the problem. Then you may repeat this step with other plugins until there are only LSP Plugins left in the session.
  If the problem will be reproducible on your session with ONLY LSP Plugins, then it's guaranteed to be a problem of LSP Plugins. Otherwise we need to find the setup when LSP Plugins start to work improperly.

Hi, I've started an empty Renoise instance without anyting else loaded than the LSP stereo limiter. The GUI of the plugin is still freezing after some seconds.
I have deinstalled all Calf plugins to make sure they don't affect LSP.

So it's definitely not the fault of any other plugin.

Now that I typed this comment I switched back into the workspace where Renoise + LSP stereo limiter are running and I noticed that the window of the plugin now shows the content of my previous workspace (the browser). Which means that the window is not redrawn / refreshed at all. I've added an attachment to illustrate that.

EDIT I've tested LSP EQ and delay plugins, same problem.

  Hello. That's more interesting.
  Is this a problem of Limiter only? I mean do other LSP plugins work properly?
  Is it reproducible on older releases (1.1.2, 1.1.1, 1.1.0) ?
  
  If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

    It happens with all plugins that I tried (4 or 5).
    I'll test with older releases asap.

Hi!
I've just released 1.1.4 version of plugins. There were some bug fixes also related to possible memory corruption. Please check the behaviour.

  Hi, sorry for the super late answer, but it isn't fixed. The GUI freezes are still occuring.
  I tested both with Renoise and Reaper, latest versions.
  
  If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
  - SadKo - 2018-12-17
    
    In the upcoming 1.1.5 release (at the end of this week), there will be many changes. I think it would be better to consider 1.1.5 a a start point.

      I've tried some plugins from 1.1.5 and I think it's good now, no GUI freezes, yey! Thanks for your support, I guess you can close this issue.
