GitLab-CI and stealing focus
gitlab-runner runs on Windows as a service. This does not have access to an actual desktop session. Generally this isn't a problem (we just have to tell Qt to use OpenGL rather than GLES), but some ParaView tests try to force focus which fails in this configuration. See .gitlab/ci/ctest_test.cmake for tests excluded for this reason.
Two possibilities:
- use a scheduled task to run gitlab-runner (might be possible, but untested right now)
- tweak tests to not need these things
