causes by the fix of the bug 199557,
before that gdb reported -1 for such case and currently we do not if it is a 64 bit register or not
Comment 3 Maria Tishkova 2017-08-11 11:04:25 UTC 
I cannot re-produce.
Comment 4 soldatov 2017-08-11 11:40:07 UTC 
On x86 Linux such test case can be used:

int main() {
    asm ("movl $0xefffffff, %eax");
    asm ("movl $0x00001111, %eax");
    asm ("movl $0x11111111, %eax");
    return 0;
}

In Register tab I see 0xefffffff
In tooltip (Disassembly tab) I see: 0xffffffffefffffff
Comment 5 Maria Tishkova 2017-08-15 09:41:17 UTC 
Fixed. Variable created for the tooltip and pinned watch for register will be formatted with current Data representation format (which is hexadecimal by default for Disassembly window) and therefore will be the same as in Registers window.
