This is caused by previous patch which tried to fix string over-read, which breaks UEFI menu rendering: the following /------------------------------------------------------------------------------\ | Device Manager | \------------------------------------------------------------------------------/ is rendered as /\ | Device Manager | \/.0 2.00 GHz (the spurious digits are SMBIOS data from the home screen) The problem appears to be that the CHAR16 value of BOXDRAW_HORIZONTAL equals 0x2500, which means that testing ArgumentString[] != '\0' (which tests the low byte only) will yield FALSE and terminate the loop prematurely.
