Bug ID: 102522 Summary: [radeonsi, bisected] commit 147d7fb772 causes full-window map to flash green in Crea Product: Mesa Version: git Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: Kaelyn.Alexi+fdo@gmail.com QA Contact: dri-devel@lists.freedesktop.org

In the game Crea (http://store.steampowered.com/app/280520 and https://www.humblebundle.com/store/crea), when opening the map to the full-window, non-overlay view on recent Mesa, the screen constantly flashes with a green hatching that makes the map impossible to make out. The flashing seems to occur between frames, since the snapshots taken by glretrace don't reflect the issue even though replaying a trace does. The problem first shows up with commit 147d7fb772 "st/mesa: add a winsys buffers list in st_context".

The apitrace https://drive.google.com/file/d/0B-61xmxFzL-fTklGMzRiSERlTUE/view?usp=sharin... shows the game loading and me bringing up the map; once the non-overlay map mode is reached is when the green flashing starts for me (when Mesa is at or past the aforementioned commit, including 17.2.0-rc5).

I'm running Gentoo Linux on a Ryzen 1800X with a Radeon RX480, and Mesa was compiled against LLVM 4.0.1 (though I usually use Mesa and LLVM git), using gcc 6.4.0 for building everything. And I'm running Xorg 1.19.3 and kernel 4.12.7.
