Launching minicap twice = permanent freeze

[grrosminet]

When launching minicap twice (from two different terminals), then second launch creates and destroy virtual display immediately (which is normal). but it freezes the screen permanently (adb still works). Need to do "adb reboot" to solve situation.

first launch log :
