 This stems from an issue filed in WooCommerce:
 https://github.com/woocommerce/woocommerce/issues/13561

 In RTL mode, pages will be blank until the window is scrolled or resized.
 This only happens in Chrome and it happens intermittently and primarily on
 admin pages (edit-posts, nav-menu, plugins, etc). I've verified this
 behavior on both existing sites using the RTL Tester plugin and on a
 fresh, Arabic WP install with no plugins. I can reproduce this on any
 default (2012-2017) theme.

 To reproduce on an existing site:
 1. Install and activate the RTL Tester plugin.
 2. Switch to RTL mode.
 3. Open an admin page (plugins.php, etc.) in Chrome.
 4. Refresh the page repeatedly.

 To reproduce on a new site:
 1. Create new Arabic-language site.
 2. Open an admin page (plugins.php, etc.) in Chrome.
 3. Refresh the page repeatedly.

 I've also been able to reproduce this on frontend pages (e.g. search
 results, "Hello World", etc.), but it seems to happen less often.
