c# - WPF application stops interacting on screen rotate -


we have wpf app runs fine, user reported locks when screen rotated. (tablets that!)

the app renders after rotate stops responding mouse/keyboard. doesn't show 'non-responding' in windows sense.

we can simulate "lock up" here, debugging odd:

  • lock not occur while in vs debugger
  • if try , attach locked process, vs says process built without debug information
  • before lockup vs can attach/deattach same exe process

we have put trace outputs in global unhandled exceptions nothing fired.

i can think of 1 next step debug start hack out chunks of code , find breaking area.

anyone seen before or got suggestions?

thanks!

the issue update library using called sparkle.

it creating hidden winforms form in it's constructor. there must kind of wpf/winforms interop bug during screen rotations. removing form or removing library fixed issue.
