SIGSEGV on launch develop version

Describe the bug
The latest develop release throws a SIGSEGV when starting Degate.

To Reproduce
Steps to reproduce the behavior:

  1. Build degate with Qt 6.5.2 GCC 64bit
  2. Launch the newly built executable in build/out/bin
  3. Critical error message.
Build ABI: 'x86_64-little_endian-lp64'
Kernel type: 'linux'
kernel version: '5.4.0-159-generic'
Current CPU architecture: 'x86_64'
Build CPU architecture: 'x86_64'
Product type: 'ubuntu'
Pretty product name: 'Ubuntu 20.04.6 LTS'
Product version: '20.04'
Degate version: '2.1.0-alpha.1'
Degate version type: 'nightly'
Degate release date: 'unreleased'
An unexpected error occurred. Error message:

'A SIGSEGV occurred (11).'

Possible fix
In MainWindow.cc the call QGuiApplication::screenAt(this->pos()) returns a nullptr on my machine. Not sure why, but it does. If I comment out that line (or add nullptr checks) the application starts just fine.
Possible fix -> Fusion86@0017bcb

Just reporting this here for completeness sake. I fixed my own issue, so feel free to close this if this doesn't belong here.

Hello, thanks for the bug report (and identifying the source). This seems to be related to #19 (Qt6 migration), something may have changed in Qt6. I will merge a fix in the next few minutes

@Fusion86 This should be fixed now with 3dc2861, can you confirm? Also thank you for other contributions related to deprecation warnings

Fusion86 commented

Yes, this fixes the issue for me. Thanks!
