If you watch YouTube on the Google Chrome internet browser, full-screening a video sometimes results in ugly white space around the edges instead of an enlarged video. The bug seems to be less common in more recent Chrome versions, but until the exact cause is pinned down by Chrome developers, you can sidestep the issue by enabling a different version of the Flash plugin.
Enable NPAPI if you are reading this after April 2015. Due to upcoming changes to Chrome, this method will require an extra step after April 2015. set the option to "Enable NPAPI" or similar. If that date is still in the future, ignore this and move on to the next step.
- Never change any other options on this flags page unless you know exactly what you are doing.
- The detailed explanation: There are two versions of the Flash plugin for Chrome, one using Chrome's PPAPI interface and one using the older NPAPI. The PPAPI version is usually the cause of this glitch. All NPAPI plugins are being phased out for Chrome due to security risks, so this extra step will be necessary to opt in to using NPAPI.
Download a different Flash player, if there is only one listed. Scroll through your list of plugins and look for "Adobe Flash Player." If it says "(2 files)" after the name and lists two instances of "Shockwave Flash" beneath it, continue to the next step. If there is only one flash player, follow these instructions before continuing:
- Open a different browser, preferably Firefox or Safari. (Chrome will only download the existing PPAPI plugin, so you need a different browser.)
- Visit adobe.com and follow the instructions to download and install flash player. This will involve relaunching your browsers, so bookmark this page or take a screenshot so you can follow the next instruction.
