Package: x2goclient (win64) Version: 4.0.5.0 (Qt 4.8.6)
Notes:
omitting the maximize (step 2) yields normal results x2goclient on linux does not suffer from this issue vnc both windows/linux does not suffer from this issue
The rest of the windows spawned by IES all suffer from this...
I haven't observed this with other programs, so I'm attaching the strace for reference.
