Spun off from bug 1720841: See https://bugzilla.mozilla.org/attachment.cgi?id=9231507 (see also testcase in url field). I see this in the latest nightly (92) and beta (91) with: Samsung Galaxy S4 (GT-I9506) Android 5.0.1 Qualcomm Adreno (TM) 330 OpenGL ES 3.0 V@84.0 Disabling webrender makes buttons look normal. I assume it happens in 90 as well but it unusable because of bug 1720841.
