I've heard of issues with windows 10 and it's display settings making filemaker behave weird.
It's probably your UHD screen and settings that are causing the issues. You might want to play around with the display settings to see if you can correct the settings to something that will work for you.
FileMaker is most likely aware of this issue since I've seen it on here before, but it's most likely up to you to set things to a compatible configuration until an update is released to support the new win10 settings.
Thank you for your feedback and thoughts Mike. Unless someone does post a solution I will continue trial and error and post any success.
Thanks, please do so I can pass it on to others.
Ok I found the solution. I changed the monitor resolution to HD (1920x1080)
Now FM displays correctly.
Hopefully, between FileMaker and Microsoft, I will be able to use the native UHD resolution of my monitor.
Unfortunately, neither this nor the 100% fix identified elsewhere have solved this display problem for us.
Windows 10 Pro (10.0.10586)
8 GB RAM
2.2 GHz Core i5-5200
Intel HD Graphics 5500
Hope there's a thorough/official fix coming soon.
