@danwalmsley I think this is Screens or WorkingArea.

[danwalmsley]

We cant implement this feature correctly until these are resolved:
https://github.com/AvaloniaUI/Avalonia/issues/3796
https://github.com/AvaloniaUI/Avalonia/issues/3795

suggest removing saving of window size? @lontivero @molnard

[lontivero]

If there is no workaround possible then remove/disable the feature.

[danwalmsley]

ok I will remove it, and ill work on avalonia side to fix the apis that will enable this.

[danwalmsley]

@634-5789 can you tell me are you using multiple monitors? and also if you remove the second monitor does the crash go away?

[molnard]

Yes, remove it. Caused so much trouble versus benefits.

[634-5789]

@634-5789 can you tell me are you using multiple monitors? and also if you remove the second monitor does the crash go away?

Two monitor setup. Laptop and external monitor as primary - if this matters. Switching to a single monitor setup fixes it indeed.

[danwalmsley]

Thanks your feedback is helpful.

[molnard]

@634-5789 this is fixed on the master. Can you confirm it by building Wasabi from the source?

[634-5789]

@molnard Built it from source, moved the ~/.walletwasabi folder and run it. Works like a charm. Thanks for fixing.

[molnard]

Thank you for your feedback. The fix will be in the next hotfix (silent) release v1.1.11.1
