Crash when navigating over blocks in diff view #1764
Description
Yesterday this crash happened twice when I pressing "next difference" (first crash) and "previous difference" (second) button in diff view. After several successful hops SourceGit crashed with the following log file (content the same in both cases, except time and memory usage):
Crash::: AvaloniaEdit.Rendering.VisualLinesInvalidException: Exception of type 'AvaloniaEdit.Rendering.VisualLinesInvalidException' was thrown. ---------------------------- Version: 2025.31.0.0 OS: Unix 6.8.0.78 Framework: .NETCoreApp,Version=v9.0 Source: <unknown> Thread Name: Unnamed User: mingun App Start Time: 25.08.2025 17:22:04 Exception Time: 25.08.2025 17:23:22 Memory Usage: 639 MB ---------------------------- AvaloniaEdit.Rendering.VisualLinesInvalidException: Exception of type 'AvaloniaEdit.Rendering.VisualLinesInvalidException' was thrown. at AvaloniaEdit.Rendering.TextView.get_VisualLines() + 0x2e at AvaloniaEdit.Rendering.BackgroundGeometryBuilder.<GetRectsForSegmentImpl>d__21.MoveNext() + 0x276 at AvaloniaEdit.Rendering.BackgroundGeometryBuilder.AddSegment(TextView, ISegment) + 0x63 at AvaloniaEdit.Editing.SelectionLayer.Render(DrawingContext) + 0x1ac at Avalonia.Rendering.Composition.CompositingRenderer.UpdateCore() + 0x9a at Avalonia.Rendering.Composition.CompositingRenderer.Update() + 0x64 at Avalonia.Rendering.Composition.Compositor.CommitCore() + 0xb5 at Avalonia.Rendering.Composition.Compositor.Commit() + 0x16 at Avalonia.Media.MediaContext.CommitCompositor(Compositor) + 0x53 at Avalonia.Media.MediaContext.CommitCompositorsWithThrottling() + 0x95 at Avalonia.Media.MediaContext.CompositionBatchFinished(Compositor, CompositionBatch) + 0x7a at Avalonia.Threading.DispatcherOperation.InvokeCore() + 0x1ba at Avalonia.Threading.DispatcherOperation.Execute() + 0x3e at Avalonia.Threading.Dispatcher.ExecuteJob(DispatcherOperation) + 0x75 at Avalonia.Threading.Dispatcher.ExecuteJobsCore(Boolean) + 0x2c at Avalonia.Threading.Dispatcher.Signaled() + 0x41 at Avalonia.X11.X11PlatformThreading.CheckSignaled() + 0x56 at Avalonia.X11.X11PlatformThreading.RunLoop(CancellationToken) + 0x280 at Avalonia.Threading.DispatcherFrame.Run(IControlledDispatcherImpl) + 0x109 at Avalonia.Threading.Dispatcher.PushFrame(DispatcherFrame) + 0x9b at Avalonia.Threading.Dispatcher.MainLoop(CancellationToken) + 0x124 at Avalonia.Controls.ApplicationLifetimes.ClassicDesktopStyleApplicationLifetime.StartCore(String[]) + 0x76 at SourceGit.App.Main(String[] args) + 0xe0 Obvious, this is some bug in AvaloniaUI, but maybe this is known bug that is fixed in new versions?
