From: Jaceee Wonders <winehq@jaceee.com> In some cases windows apps may try to draw large cursors that exceed hardware accelerated cursor rendering on x servers. Ex: with nvidia proprietary the values may be: ``` $ xdpyinfo | grep -i cursor largest cursor: 256x256 ``` In such cases (even with 96dpi) on some x servers like xorg/xlibre cursor rendering may be unstable (rendering artifacts, flickering). Patch introduces optional logic path (manual toggle) that will attempt to conform win/x cursor to that of best reported by x. Note: Original hotpath is untouched. * create_xcursor_cursor - decouple windows cursor buffer from x cursor buffer, buffer dimensions logic * create_xcursor_frame - support target buffer dims != soruce buffer dims * two config fields toggling best cursor modes (if best cursor is smaller than requested cursor): - clamp_x_cursor_to_best_size: win cursor buffer will be clamped to max dimension values of the best cursor - fit_w_cursor_to_best_size: win cursor buffer dimensions will be reassigned to smaller value that fit best cursor dimensions --- dlls/winex11.drv/mouse.c | 94 +++++++++++++++++++++++++++++----- dlls/winex11.drv/x11drv.h | 2 + dlls/winex11.drv/x11drv_main.c | 8 +++ 3 files changed, 91 insertions(+), 13 deletions(-) diff --git a/dlls/winex11.drv/mouse.c b/dlls/winex11.drv/mouse.c index f66ba639937..8ea04bbda68 100644 --- a/dlls/winex11.drv/mouse.c +++ b/dlls/winex11.drv/mouse.c @@ -580,7 +580,8 @@ static void send_mouse_input( HWND hwnd, Window window, unsigned int state, INPU static XcursorImage *create_xcursor_frame( HDC hdc, const ICONINFOEXW *iinfo, HANDLE icon, HBITMAP hbmColor, unsigned char *color_bits, int color_size, HBITMAP hbmMask, unsigned char *mask_bits, int mask_size, - int width, int height, int istep ) + int width, int height, int istep, + int x_width, int x_height) { XcursorImage *image, *ret = NULL;
