I have checked material code and this behaviour is because of class mat-sidenav-content which has transform property. There are two tickets about this issue in material repository https://github.com/angular/material2/issues/4873 and https://github.com/angular/material2/issues/998

At this moment there is one option to fix this behaviour

.mat-sidenav-container, .mat-sidenav-content {
    transform: none !important;
}
