Bug ID: 105282 Summary: Divinity: Original Sin Enhanced Edition blocky and jagged shadows. Product: Mesa Version: 17.3 Hardware: All OS: Linux (All) Status: NEW Severity: enhancement Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: e.singularitycat@gmail.com QA Contact: dri-devel@lists.freedesktop.org

After working around the bugs described in #93551 and getting the game running, I noticed that unless the shadow quality setting was at "Ultra", all rendered shadows are blocky and jagged, with gaps appearing between the shadows cast be apparently solid objects.

I messed around with some driconf options, and discovered that this rendering issue goes away if setting the "glsl_correct_derivatives_after_discard" option.

Unfortunately, I couldn't get a working apitrace because of the LD_PRELOAD hacks, but attached are two screenshots of roughly the same area, one without the option (before.png) and one with (after.png).
