Short description of error
Title Bar size remains constant size (in pixels) when moving Blender Window between monitors with different DPI and Scaling settings in WIndows 10
Exact steps for others to reproduce the error
- Open Blender in High DPI monitor. Everything appears properly Scaled.
- Move the same window to a Normal DPI monitor. Everything in the Blender Window appears properly scaled, except for the Window Titlebar, which appears to be too big. This is because the Titlebar retains the height in pixels from the monitor it was originally opened on.
Reversing this procedure and opening Blender on a Normal DPI monitor and moving to a High DPI monitor also causes very small Titlebar.
Solution would be to reset the height of the Titlebar whenever the window is moved to a new monitor, just as the rest of the Blender Interface is redrawn for every such move.
