Mouse pointer disappears on Win 10 2004 19041.508 (latest update 09/2020). Display driver is AMD FirePro W4100 displaying at 8192 x 2160 across 2 displays or 4096 x 2160 on a single display. Also tried reducing resolution to 1920 x 1200. Chitubox versions 188.8.131.52 Beta & 1.5 have the same problem on all these resolutions - mouse pointer disappears after first click. Mouse still works, highlights icons when hovered over, but difficult to work out where the pointer actually is. Pointer trails not working, neither does show location when control key pressed. Have to end Chitubox via End Task in Task Monitor to get out of it.
Tried that - mouse works OK everywhere else. I am using 2 x 43" (109cm) 4K displays. Reset mouse pointer & text font to default sizes - same result. Had the same problems on earlier version of Windows 10 (1907) and earlier versions of Chitubox . Cure, then and now, was always to set the Chitubox window smaller than full screen as the first mouse click. When not full screen the mouse works normally in Chitubox
