What you need to know
High-refresh-rate support improved in v1.0.5. Use the current v1.0.6 build when checking it: v1.0.6 corrects the swapped Fullscreen and Borderless modes, but does not announce a new high-refresh-rate improvement.
Confirm the current build
Older reports may describe behavior changed by v1.0.5. Check the installed version before comparing display behavior.
Check the active display
In v1.0.6, Fullscreen and Borderless modes now correspond to their intended settings. Record the monitor refresh rate and the display mode in which the problem occurs.
Use evidence for escalation
A useful report includes hardware, refresh rate, observed symptoms and reproduction steps. No universal external frame cap is verified here.
