Re: BETA: NoesisGUI v2.1.0rc3

re: ghost lines conversation from page 8: just did some tests on iPhone X with 2.1rc3, and I see lots of ghost lines on edges of controls. You fixed this in beta17 and i confirmed OK (was using Android.) Do we also need the same or further fix for iPhone? btw, I don't remember seeing the ghost lines...

Re: Noesis memory fragmentation crashes - how to avoid?

Thanks! We're experimenting by assigning the images as TextureSource after the XAML loads, then we can see if that part of the load/unload causes fragmentation

Re: IsHitTestVisible has no effect?

It's a bug in WPF that Noesis is keeping for compatibility. http://www.noesisengine.com/forums/sear ... estvisible
I think there should be an option to run Noesis with the bug fix. Or just fix it. :)

Re: Noesis memory fragmentation crashes - how to avoid?

Thanks for the info! Clues - somewhat. We did (a lot) more tests and found out that: 1. When we reload XAML views and synthetic test (important,) the app crashes after 105-130 iterations. Black screen on iteration 5 due to rendertexture alloc failure (GPU memory fragmentation.) 2. Without XAML views...

Re: Noesis memory fragmentation crashes - how to avoid?

Thanks for the suggestions - trying! This is very helpful info! Yes, I suspect it's GPU since after some test iterations we get a "GL_OUT_OF_MEMORY: Not enough memory left to execute command" error. This said, in several cases we'd get the GL_OUT_OF_MEMORY, but the app wouldn't crash immediately - j...

Noesis memory fragmentation crashes - how to avoid?

Context: Our app is an image editor and is very UI-heavy. We noticed that it crashes during stress testing doing the following repeatedly: 1. Open an image 2. Going through few XAML screens (just to select effect below) 3. Run simple "convert to grayscale" effect on GPU 4. go to 1 After a week of in...

Re: BETA: NoesisGUI v2.1.0rc2

@nokola, I never thought about this case. I think it should not be hard for the Noesis team to just add a simple flag which will avoid returning elements with IsHitTestVisible==false. Full delegate approach as in WPF will be much harder to implement due to C#-to-C++ interop... and I really can't se...

Re: BETA: NoesisGUI v2.1.0rc2

re: HitTest, added ai_enabled's suggestion (good one) to the bug I have opened previously for HitTesting - http://www.noesisengine.com/bugs/view.php?id=1222 Would be best indeed to have extra overload to allow circumventing WPF's problematic behavior. Edit: Update on the other jittery scrolling issu...

Re: BETA: NoesisGUI v2.1.0rc2

Thanks! Unfortunately, going to parent won't account for the case when we have the child outside of parent (e.g. 0-sized canvas), which is a common case if you want to render on exact pixel coords.
