This reduced the amount of memory not deallocated by windows but there

Put a printf() in the other XSetClip function to see whether
this might be the other leak, or whether we should still look
hard at ChProperties.c
Some long time ago I had that problem with XSetClip() and FLTK too and made a modification that
solved the problem for me.

int XSetClipMask(Display *display, GC gc, Pixmap mask)

static GR_GC_ID last_gc_gid = 0;

GR_WINDOW_INFO info;
// to avoid a memory leak, delete region if last region hasn't been
deleted before
if ( (last_gc_gid == gc->gid) && (last_region != 0) )

GrDestroyRegion(last_region);
//printf("XSetClipMask remove %d %d %d\n", mask, last_gc_gid, last_region);
last_region = 0;
last_gc_gid = 0;

//printf("XSetClipMask NO remove %d %d %d\n", mask, last_gc_gid, last_region);

GrSetGCRegion(gc->gid, 0);
