Gnome Xwayland, Debian Testing, Intel This seems to be an earlier partial present regression that was caused by bug 1704956 and not by bug 1706488 (bug 1712969). STR: Hover the video shortly. Expected: When unhovering the video, the video should no longer be visible. Only the image should be visible. Actual: The glitch occurs at the top or at the bottom of the video player: A part of the video remains visible. It may even consist of multiple stripes with correct content in-between. mozregression --good 2021-01-20 --bad 2021-04-20 --pref gfx.webrender.all:true -a https://www.dw.com/en/sudan-gold-mine-collapse-kills-dozens/a-60281945 > 31:54.34 INFO: Last good revision: 0639a51e1f164a99e5be8d056e6a9bfb29242c7a > 31:54.34 INFO: First bad revision: 2df08c0b8938005b211e18fa85c7696a758cdc5c > 31:54.34 INFO: Pushlog: > https://hg.mozilla.org/integration/autoland/pushloghtml?fromchange=0639a51e1f164a99e5be8d056e6a9bfb29242c7a&tochange=2df08c0b8938005b211e18fa85c7696a758cdc5c > 2df08c0b8938005b211e18fa85c7696a758cdc5c Glenn Watson — Bug 1704956 - Support non-opaque compositor surfaces. r=gfx-reviewers,lsalzman Reproducible with: * EGL (screencast): mozregression --launch 2021-12-28 --pref gfx.webrender.all:true gfx.x11-egl.force-enabled:true -a https://www.dw.com/en/sudan-gold-mine-collapse-kills-dozens/a-60281945 * GLX: mozregression --launch 2021-12-28 --pref gfx.webrender.all:true gfx.x11-egl.force-disabled:true -a https://www.dw.com/en/sudan-gold-mine-collapse-kills-dozens/a-60281945 GLX can be fixed with gfx.webrender.allow-partial-present-buffer-age:false or with gfx.webrender.max-partial-present-rects:0: * mozregression --launch 2021-12-28 --pref gfx.webrender.all:true gfx.x11-egl.force-disabled:true gfx.webrender.allow-partial-present-buffer-age:false -a https://www.dw.com/en/sudan-gold-mine-collapse-kills-dozens/a-60281945 * mozregression --launch 2021-12-28 --pref gfx.webrender.all:true gfx.x11-egl.force-disabled:true gfx.webrender.max-partial-present-rects:0 -a https://www.dw.com/en/sudan-gold-mine-collapse-kills-dozens/a-60281945 In contrast to bug 1712969 and its duplicates, gfx.webrender.allow-partial-present-buffer-age:false seems to help a bit on EGL: The glitch occurs, but quickly disappears. mozregression --launch 2021-12-28 --pref gfx.webrender.all:true gfx.x11-egl.force-enabled:true gfx.webrender.allow-partial-present-buffer-age:false -a https://www.dw.com/en/sudan-gold-mine-collapse-kills-dozens/a-60281945 gfx.webrender.max-partial-present-rects:0 fixes EGL: mozregression --launch 2021-12-28 --pref gfx.webrender.all:true gfx.x11-egl.force-enabled:true gfx.webrender.max-partial-present-rects:0 -a https://www.dw.com/en/sudan-gold-mine-collapse-kills-dozens/a-60281945
