+Subject: [PATCH] egl/x11/sw: fix partial image uploads
+
+* swrast allocates images aligned to 64x64 tiles, which results in images
+  that are larger than the window. PutImage requests must be clamped on
+  the y-axis to avoid uploading/damaging out-of-bounds regions
+* winsys coords are y-inverted
