@Alexander Halser A few years ago I made a tutorial on how to explore iOS app crash, but the same applies to macOS as well. Take a look especially at Step 4 - Symbolizing the crash file.

@Riku23 Can you attach a demo? Are you using Skia? I’m asking this because Skia is rendering its own filters on RAD 12+, so you can get different results when Skia is enabled. Let me know if this is the case.

@John van de Waeter The performance with Skia was improved on RAD Studio 12.2. Also, the property Form.Quality affects the performance when Skia is enabled. Note: I recommend delete your project dcu output folder as it may contain old versions of Skia4Delphi from the open-source installation.

Seems related to “Display zoom” option of iOS. Issue reported here: https://github.com/skia4delphi/skia4delphi/issues/315

@XylemFlow are you using GlobalUseSkia := True;?

Also, the adaptive icon files, and all artwork generated files, are available at your project folder, in the subpath “.\<ProjectName>.Artwork\”. It is important to note that the adaptive icon and the vectorized splash are only generated when you use and SVG on the input of icon fields of the artwork generator. That is, if you use PNG image, it will generate all icons and splashs but not the android adaptive icon and android vectorized splash. If you found a real issue in the IDE and you have the steps to reproduce, please create a Jira for it, to improve future versions.

Try add GlobalUseMetal := True; on your dpr. iOSSim has one know issue related to OpenGL.

@Hans♫ I think that could be a Google Skia limitation or issue, so the right place to report bugs is on https://issues.skia.org/, instead on QP. However, I have already opened a new conversation in the Skia group to obtain more information about this: Poor quality of anti-aliasing on NVidia GPU (google.com)

@Hans♫ I used the same code you provided and got satisfactory results. Look: <No Skia> | <Skia + Vulkan> (Scale 100%) It is difficult to deduce what is happening if the same code is producing different results. That's why I think it would be interesting if we could test it on more machines. The project I used is attached: testVulkan.7z

@Hans♫ Do you have a blank project simulating this? I drew directly in the form's OnPaint using your example on a blank project and got the same result for all renders, except for the FMX GPU without Skia which seems to be bugged. scale 1x: scale 2.25x:

@Hans♫ Is this an image or a path? (we have to understand if the arrow is being drawn or resized) Can you share the source of this icon?

@Hans♫ Please check your Form.Quality because the AntiAlias is direct related to the current form quality: https://github.com/skia4delphi/skia4delphi/blob/093ec41b1b951c68cbccaa885a84c19242e09fb7/Source/FMX/FMX.Skia.Canvas.pas#L1571 The AntiAlias of raster is forced to be always true because some preliminar tests proved to be apparently faster.

@Stefan Glienke Could you add a version constant to Spring.pas? Something like: const Spring4DVersion = 2.0; to help us maintain code compatible with 1.x and 2.0 at the same time, as it would allow: {$IFNDEF DELPHI_12_UP} constructor THashSet<T>.Create(ACapacity: NativeInt); begin {$IF defined(Spring4DVersion) and (Spring4DVersion >= 2)} inherited Create(ACapacity, nil); {$ELSE} inherited Create; {$ENDIF} end; {$ENDIF} This is especially important for large teams/projects that share common code, where some projects and people use version 1.x while others use version 2.x, and the common code should support both.

Hi @martincg! I answered you on another topic with the same issue. To preserve the old content of the bitmap when starts draw with skia, you should call Bitmap.SkiaDraw(..., False);

@martincg Bitmap.SkiaDraw have a second optional argument, AStartClean: Boolean, and when False you will not lost its content.
