Fix garbled text when display scalling > 300% (#3402)
* Fix garbled text when display scalling > 300% On Windows, if your display scaling is greater than 300%, the text rendered by imgui will be garbled. Allowing imgui to do the scaling instead of making the font to large corrects the issue. * Only use modified scaling on Windows And only if the system's scaling factor is greater than 300%. --------- Co-authored-by: SoftFever <softfeverever@gmail.com>
