Summary: Oblivion: blank screen when HDR is enabled Product: Wine Version: 1.1.20 Platform: PC-x86-64 OS/Version: Linux Status: UNCONFIRMED Severity: minor Priority: P2 Component: directx-d3d AssignedTo: wine-bugs@winehq.org ReportedBy: roothorick@new.rr.com
In Oblivion, if you turn on HDR, all you get is a blank screen of some color appropriate to the setting you should be seeing (e.g. sky blue if you're outside in broad daylight), with the HUD elements overlaid upon it. If you disable HDR and restart Oblivion, you can see again.
I can only speculate that the shader Oblivion uses for HDR isn't translated properly (at all?) and as a result nothing is actually rendered.
