Hello Guys,

Please really help with understanding it.

I signed component & installer and notarized it. There are no problems with the signature. As soon as I open the plugin on another device I get this problem.

Nothing to do with notarisation - it’s trying to open a UI and are loading a bitmap which is not at the same scale as the machine. iPlug2 attempts to scale it using the graphics backend (skia) but something in skia fails on the machine you are testing on.

This might be an iplug2 bug, or it might be to do with the hardware you are running on - not sure - whatever it is is capable of running Catalina, so I assume it can’t be that old. Hard to say more without being able to reproduce.

Do I do everything correctly in this part of the code?

That looks fine - I don’t think this is a bug in your code.

Can you please try:

1 - compile with NanoVG instead of Skia and test again  
2 - Instead of IGRAPHICS\_SKIA IGRAPHICS\_METAL please also try with IGRAPHICS\_SKIA IGRAPHICS\_CPU and test again

Knowing what happens in these cases will give a clearer idea of what the issue might be.

I changed:

EXTRA\_ALL\_DEFS = OBJC\_PREFIX=vIPlugEffect SWELL\_APP\_PREFIX=Swell\_vIPlugEffect IGRAPHICS\_SKIA IGRAPHICS\_GL3 IGRAPHICS\_VSYNC

to

EXTRA\_ALL\_DEFS = OBJC\_PREFIX=vIPlugEffect SWELL\_APP\_PREFIX=Swell\_vIPlugEffect IGRAPHICS\_SKIA IGRAPHICS\_CPU

it works. Thanks!!

OK - thanks - then there is some issue with GL3 graphics on Mac - Can you add an issue to GitHub here - (if necessary just link to this post with a brief description)?

You will have to provide more detailed info about the system and code if you expect us to even consider this. It’s not worth posting anything like this if you don’t provide a lot of details - how do we know you didn’t do something really crazy in your code or perhaps you are trying to run it on a really low spec system ?

Try to be as methodical as possible when reporting a problem. If something crashes, debug it and provide a crash report. If something is slow, profile it and find out where it is slow

We’ve been trying to figure out what the problem is for a week. I hope this is more than described in detail, what we do in the code. Specifically, all graphics modes work on my machine. But as soon as I notarize the package and send it to the test bench, I get endless errors for everything except the CPU

I can’t understand what notarising would have to do with it, but I’ll try soon

I’ve heard of numerous developers who experience slow graphics on the 5k retina iMac’s

e.g [https://user.cockos.com/~deadbeef/index.php?article=697](https://user.cockos.com/~deadbeef/index.php?article=697)

But this does not explain one thing, why the plugin crashes when starting in any modes other than CPU

So, when I trying to run plugin on test machine, that I present upper in a topic (macOS 10.15.6 5k), Logic and other apps in which I running this plugin is crashed.

Looks like iMac hardware doesn’t support METAL or GL or system doesn’t want to enable gpu for application. IDK, maybe problem in mac coz on another machine plugin running in any mode. But its look so strange. I will try to test on another one device but may be smb already know and fix this issue.

After a lot of tests. I found problem parts of code:

```
  /*
  bitmap = pGraphics->LoadBitmap(ARROW_FN, 128);
  pGraphics->AttachControl(new IBitmapControl(1705, 160, bitmap, kL));
  pGraphics->AttachControl(new IBitmapControl(2055, 160, bitmap, kR));
  */

```

All moving objects (knobs, arrows) cause a crash.

something todo with your bitmap i think and the scaling. like @AlexHarker said . do you have a @2x version of the bitmap (it still shouldn’t crash) ?

It’s possible this is to do with frame buffers in relation to the CPU and GPU (as the problem with nanovvg) but we do need to be able to replicate in order to fix.

@olilarkin @AlexHarker

I made a test project with these graphics, sorry for the large repository. I do the same thing in my big project.

The problem is vu\_arrow.png. For nanovg images can not be taller than 16384 pixels, so it crashes.

With Skia it crashes when loading on retina screen during the resizing of vu\_arrow.png. If I place a 2nd resized version vu\_arrow@2x.png next to the original, there is no crash. I also re-saved the original file with photoshop and now it seems to work without crashing, even without the @2x version.

Also,

instead of calling pGraphics-\>resize(), where you do, just specify a scale in MakeGraphicsFunc…

````auto
        mMakeGraphicsFunc = [&]() {
          return MakeGraphics(*this, PLUG_WIDTH, PLUG_HEIGHT, PLUG_FPS, 0.58);
        };```
````
