After updating to VS 2026 v18.4.1 there is a 10X slowdown in compiles and hangs indicating ReSharper extension needs to be disabled?
This ONLY started after updating to VS 18.4.1. So I checked the JB logs and found the .err.log with listed exceptions that appear to be JetBrains code issues. JB ReSharper version 2025.3.3.
Message = “Field 'Microsoft.VisualStudio.Text.Editor.Implementation.GlyphMarginVisualManager`1[Microsoft.VisualStudio.Text.Editor.IGlyphTag]._visuals' not found.”
InnerException = “Exception #1 at Root.InnerException”
My workflow has come to a crawl, can't really work like this due to performance issue. Any solutions or work arounds?

Hi, Robin.
I am using version 18.4.2 and cannot reproduce the issue. The exception you mentioned should not impact performance. Could you please take a performance snapshot using the following manual? https://youtrack.jetbrains.com/articles/SUPPORT-A-2191 .Thanks!
18.4.2 just dropped today, let me try that and see if the issue resolves. If not, I'll follow your PerfView process and report back.
We were informed through the Support channel that upgrading to version 18.4.2 resolved the issue.
We were pleased to hear that!
