From 747d7ad231a0955991e179deb482ce94376f1e17 Mon Sep 17 00:00:00 2001 From: BALATON Zoltan Date: Sun, 11 Aug 2019 23:14:53 +0200 Subject: ati-vga: Fix hardware cursor image offset The crtc_offset is not needed, cur_offset is relative to the start of vram not the start of displayed area. This fixes broken pointer image with MacOS that uses non-0 crtc_offset.
