WORKAROUNDS TESTED Tried using the Intel driver in SNA/UXA and DRI2/DRI3 settings, tearfree ON/OFF to no avail Tried using the modesetting driver, same results This glitch also happens with window decorations fork like SierraBreeze and SierraBreezeEnhanced Aurorae window decorations are unaffected by this bug
