@ekianjo : no that will not, only smoothness of the picture. But you use this version, be sure to select windowed and no scaler, that will improve speed, and probably touchscreen. @sepulep ; so I have integrated your changes for next release. The "touchscreen" changes (about the mouse pointer) is all behind a new parameter (in [sdl] that is touchscreen=true/false, false be default) and the click_mod. And I have adapted dbgl for those 2 new parameters. What should be the default value for that click_mod, to have it on some shoulder button (maybe I should put that on the tooltip on DBGL)?
