Direct2D debug messages

[fuo]

Hi @matt

Yes, these exceptions seem to be gone.
I do see other exceptions popup now, not sure if they were there before as they are much less frequent:

• Microsoft C++ exception: CacheOverflowException when the text is updated frequently
• The thread 'JUCE D2D swap chain thread' (XXX) has exited with code 0 (0x0) in popupmenus

[matt]

Right on - thanks for trying the patch.

[matt]

Good to hear the patch improved matters.

Microsoft C++ exception: CacheOverflowException when the text is updated frequently

Are you recreating the typeface every time you paint or just creating it once?

The thread 'JUCE D2D swap chain thread' (XXX) has exited with code 0 (0x0) in popupmenus

That’s to be expected - every heavyweight window has its own swap chain with its own dedicated thread.

Matt

[fuo]

Hi @matt

I was indeed recreating the typeface in my test code!

@matt

That’s to be expected - every heavyweight window has its own swap chain with its own dedicated thread.

OK I see.
I get 5 of these messages every time a menu is closed though.
It gets noisy when browsing a menu with submenus

[jdv]

@fuo

I get 5 of these messages every time a menu is closed though.

For what it’s worth, the Visual Studio output window has a setting to disable this message: c# - Is there a way to prevent Visual Studio from printing Thread exited statements into the Output Window? - Stack Overflow

[fuo]

Now that the noise level is lower (thanks @jdv!) I see other exceptions in my app as well as in the most basic GUI project template:

Object dump complete.

I get these with all JUCE 8 versions I have tried, but not with either JUCE 7.0.10 or JUCE 7 Direct2D.

[Toddler-Boy]

Are you running this under some sort of virtualization or emulation?

[fuo]

No, this is a Windows 11 install.
Might still be the fact that I don’t have a dedicated GPU?

[Toddler-Boy]

No idea, but when searching for MONZA, it comes up with some Microsoft stuff for virtualization.

Also comparisons with the JUCE7 D2D are not really valid anymore, as a LOT has changed since then. Especially when it comes to text rendering. It’s like saying “the new code behaves differently than before it existed”.

I’m not getting any of these exceptions so it might really be driver thing.

[matt]

I suspect the leaks are from the Harfbuzz library.

You can set Visual Studio to break when the exception happens to get a stack trace. Go to Debug/Windows/Exception Settings and enable all the C++, common language, and Win32 exceptions.

Matt

[matt]

Comparing the JUCE 7 vs JUCE 8 renderers is still useful for me, at least for now.

[Toddler-Boy]

igd10um64xe.dll is the Intel GPU driver. Wasn’t recently some code changed in JUCE8 regarding DPI stuff?

[fuo]

I updated my Intel driver to the last version (from 4 days ago) with no difference.
I suspect all these recent updates are for dedicated ARC dedicated graphic cards and the new Xe in laptops.

[fuo]

I just tried with a 100% DPI setting (was 200%), same exceptions and leak.

[matt]

Is that call stack from the message thread?

[Toddler-Boy]

The scale doesn’t matter. The calls to the API still have to be made to find out the current desktop scale, etc. I’m just trying to provide context.

[fuo]

More details.

[matt]

OK, I take it you’re seeing an exception when the adapter is released?

Matt

[fuo]

I couldn’t say.
I have a series of 8 exceptions when the application is created, and then 2 exceptions when it is shutdown.
If you need me to test specific things let me known.
