Changing the resolution of a Thrower/Video screen with eDMX fixtures mapped to it causes a crash

Lightact crashes when you change the resolution of a Thrower or a Video screen that’s set up as the source of a Fixture or a Fixture placement.

Steps to reproduce

1. Create a Thrower or a Video screen
2. Create an eDMX Fixture or a Fixture placement
3. Set the Source of the Fixture or Fixture placement to the Thrower or the Video screen you created in step 1
4. Change the resolution of the Thrower or the Video screen and the program will crash.

Workaround

Delete the Thrower or the Video screen and create a new one. Set the correct resolution before setting it as the Source of your fixtures.
