as the title says, current driver versions are not correctly displaying the ui of sidefx Houdini on systems using the iris plus graphics 640 or similar.
As far as I can tell the problem occurs on recent hardware like the surface pro 7 (all available driver versions) or current gen dell XPS machines.
It seems that this behavior was introduced with current drivers (above 25.xx) as there are reports, that older drivers are working fine. Sadly those are not available for the latest cpu generations (ice lake / iris plus 640 i.e.) and so the software is unusable with said hardware.
