Open rageworx opened 3 years ago

Strange, there's some trails left ... RGB_Image always filled in zero buffer, but why previous render lefts shadowed trails ?

Maybe it is only occurs on case pf 125% high DPI of Windows 10.

100% Crop of text region, it seems to new GDI double resampling by Windows 10.

new GDI high DPI resampling affects highly clear true type fonts over 100% ratio. Windows makes double sized DC by actual window size, and it draw anything on double sized, then downscale to desktop DPI ratio by 125, 150 and 175%. When doing downscaling with FLTK, there's left some stained or something uncompleted line or rectangles left sometimes, and this looks stained, or trailed shadow something may belong to MS downscaling effect.
