An Open source project, FlScrnShot updated to version 0.1.9.20 with fixing memory leakage.
I found huge memory usage on my gaming desktop ( AMD Ryzen5600 + nV RTX3080 + 64GB RAM ) while playing Red Dead Redemption 2 and Hogwarts Legacy, up to 6GB memory occupied.
It was belonged to updating FLTK 1.4.0.9 latest version changes with fl_imgtk has unmatched, and changed some rule of memory freeing on fl_imgtk. And now fixed it.
It may useful to match to capture key to “PrtScrn” as well as playing game on HDR mode. Steam client cannot handle HDR screen to JPEG-YUV420 format. FlScrnShot handles HDR image to automatically SDR and writes image to YUV444, lesser loss of HDR color space.
