Thank you ralphje , you just made my day.
I was fighting with this bug since I have started using VMware Workstation v13 on openSUSE with KDE Plasma maybe a year ago. I have second keyboard layout for Lithuanian language on host and didn't think that this can cause this annoying issue. As you said win10 VM when clicking on Start or on some other apps in some particular places, not everywhere. Or sometimes when you want to select the text then it acts as the zoom on the web browser.
@VMware please chase the bug.
This is happening to me as well with an Ubuntu host using a French keyboard layout and a Windows 10 guest.
In addition to moving scroll bars and dropdown select boxes, it makes browsers jump from tab to tab in the guest.
I have tried remapping the shortcuts as suggested with no relief.
This drives me crazy every single day.
VMware is aware of this issue, and we're working on a fix for a future version of the product.
I can confirm this endless scrolling problem with VMware Workstation 15 Player on an Ubuntu host with a Windows guest.
Indeed, selecting the first input method solves the problem. I look forward to an update that addresses this issue.
