Hi. Sure I can provide the info and screens you need.
As for your first question, I am running a 1920x1080 resolution on my desktop. When I manually select this resolution in the Video options, the config shows "Desktop Resolution" after saving and reopening the options.
So here the screenshots I took to explain my problem.
First a screenshot of a
Discord window and of
another game in windowed mode.Please note the correct window titles and the visibility of the windows task bar.
This
screenshot shows Bannerlord in windowed mode, desktop resolution.Please note the missing windows task bar and the strange title of the window. Also note the partly cut-off part of the GUi at the bottom.
For comparison a
screenshot of Bannerlord in Borderless-Fullscreen mode.The GUI at the bottom is now fully visible, nothing is cut off.
Hope this helps.
