Bug when maximizing the window. I'm trying to maximize the window (not fullscreen mode, just expand the window to fill the entire screen using the button) on a monitor with negative pixel coordinates on the X-axis (see the screenshot of the monitor settings). Then the window tries to stretch incorrectly, lags, and the result can be seen in the screenshot. This does not occur on other monitors.
The bug occurs in the "strechable, 32bit OpenGL by Verok" graphics mode; the last two updates did not help (screenshot).
