My windows DPI scaling is set to 200%, as my resolutions to 2000x3000.
If I load fiddler normally, I see the following blurry text.
So i saw this bug report, https://feedback.telerik.com/fiddler/1361354-hope-the-fiddler-can-support-the-high-dpi-screen which suggested to load up fiddler with -dpiaware, and now some text is better, but most of the tabs and buttons are incorrect sizes in the composer. In my opinion its more usable with the blurry text. I also tried to change the Fiddler.exe.config - EnableWindowsFormsHighDpiAutoResizing from true to false, but the only affect this had was to change the size of the mouse cursor.
Any ideas on something else to try, or is this a limitation of Fiddler / .Net WinForms.
