Resolution of desktop is OK and at 100%. If I set the recording window to 16:9, for example, and try to drag the corner of the recording frame to resize, the frame will drag down, or drag right, but will not do both. Shift + drag doesn't help. Alt + drag doesn't help. I don't see a lock aspect ratio button/setting anywhere. This behavior happens on Windows 10 for my and my colleague.
Has anybody seen this maddening behavior? Is there a fix?
