http://bugs.winehq.org/show_bug.cgi?id=58827 --- Comment #14 from Craig Schulstad <craigaschulstad(a)gmail.com> --- Having some time to do a bit of research in the Mahjong logs, the few information lines that stood out to me focused on an incapability of creating a display context noted by the following log lines almost at the end of the "after" log and right before the window gets destroyed. 0024:trace:opengl:wglCreateContext hDc 40010062 0024:trace:wgl:win32u_wgl_context_reset context 0x7c4cd4e0, hdc 0x40010062, share (nil), attribs (nil) 0024:trace:wgl:get_dc_pixel_format 0x40010062/0x40068 -> 0 0024:trace:x11drv:destroy_whole_window win 0x40068 xwin 5600003/0 0024:err:d3d:wined3d_adapter_gl_init Failed to get a GL context for adapter 0089F788. Working my way back through the various program files in the "win32u" dll folder, the program of interest seems to be "opengl.c". In comparing the previous version of Wine that works for me (10.15) to subsequent versions, there is a new function named "init_device_info" that updates a function pointer "compat_context = funcs->p_eglCreateContext( egl->display, config, EGL_NO_CONTEXT, context_attribs );". That might be a spot to investigate. -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.
