<div style="margin: 8px 0; padding: 0 12px; color: #74777D;"><p style="padding: 0; margin: 8px;">Ok I realize now that the extension name begins with GL_ and this is the reason it didn't find them.<br />
BUT then I listed all the available extensions and since they are in alphabetical order I can easily check if texture_barrier is available.<br />

The red arrow is where they should be but they aren't present.<br />
So my point still stands.</p></div></div>
<div style="margin: 8px 0; padding: 0 12px;"><blockquote style="border-left: 3px solid #a7b5bf; color: #464c5c; font-style: italic; margin: 4px 0 12px 0; padding: 4px 12px; background-color: #f8f9fc;"><p style="padding: 0; margin: 8px;">GL_ARB_texture_barrier is supported since OpenGL 4.4, but KWin uses 3.0<br />
GL_NV_texture_barrier is supported since OpenGL 3.0 but it only works on Nvidia right?<br />
What about AMD and Intel GPUs then?</p></blockquote>
<p style="padding: 0; margin: 8px;">The 3.1 backend can and does use some GL 4 extensions, but it must have a fallback path for when they are not available.</p>
<p style="padding: 0; margin: 8px;">The NV prefix only tells you which vendor created the extension, not which vendors support it. The AMD drivers in Mesa have supported texture_barrier since 2011, and the i965 driver has supported it since 2015.</p>
<p style="padding: 0; margin: 8px;">But as I said on IRC, don't worry about it if your driver doesn't support it. We can add a path that uses texture_barrier after this has landed.</p></div></div><br /><div style="border: 1px solid #C7CCD9; border-radius: 3px;"><div style="padding: 0; background: #F7F7F7; border-color: #e3e4e8; border-style: solid; border-width: 0 0 1px 0; margin: 0;"><div style="color: #74777d; background: #eff2f4; padding: 6px 8px; overflow: hidden;"><a style="float: right; text-decoration: none;" href="https://phabricator.kde.org/D9848#inline-45745" rel="noreferrer">View Inline</a><span style="color: #4b4d51; font-weight: bold;">blur.cpp:255</span></div>
