Just reporting another high-DPI issue I'm seeing on my mixed-DPI multi-monitor setup. I'm running DisplayFusion v8.0b5 with three displays: Primary is 3200x1800 w/ two external 1920x1080 displays.
When opening the Start menu on either of the secondary displays the DPI scaling is completely broken. It appears to be using the primary display's DPI setting for some UI elements and appropriate scaling for other parts, resulting in a very mismatched and borderline unusable UI.
I am using Start10 so it's possible this is entirely in Stardock's ballpark and I should get in touch with them, but I'm unclear what the split is here between DisplayFusion & Start10, so though I'd ask here first. I admit it, I'm in part doing so because support here is great
Some sample pictures illustrating the problem are attached.
Unfortunately this is mostly a limitation of the method we have to use for invoking the Start menu from our taskbars. DF has to simulate a click on the Start button on the Windows taskbar, then hook it and move it to the DF taskbar. The problem there, is that Start10 reads the scaling level from the primary monitor before it gets moved to the DF taskbar.
We'll try to get in contact with Stardock's dev team to see if there's a way we can open Start10 directly on the monitor with the DF taskbar, rather than having to use our current method
