+Subject: [PATCH 50/51] LibVNCClient: Fix regression in Tight/Raw decoding
+
+Introduced by d7b1462 in LibVNCServer 0.9.12. This regression caused
+the pixels in some RFB rectangles to become corrupted/garbled when the
+Tight encoding was used, without the JPEG subencoding, with a 15-bit or
+16-bit color depth.
+
+Fixes #335
+Fixes https://gitlab.com/Remmina/Remmina/issues/1824
