<div dir="ltr">I can reproduce this issue with PV 5.4 on my 4600 system. 99% sure it is a Qt bug we already bumped into with Mesa. They have what looks to me like some odd bad logic on windows for creating a context where they will not give you a core context later than the latest compatibility context they can get. For some vendors that is fine but for others they only offer Comp contexts up to 2.1 or 3.0 but not 3.2. So while the driver may support OpenGL 4 in Core mode, Qt restricts you to 3.0. I suspect if they fixed that the issue would go away. I believe Ben filed a bug report with them (Qt) when he bumped into this when using Mesa on Windows.<div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, May 25, 2017 at 7:44 PM, Elvis Stansvik <span dir="ltr"><<a href="mailto:elvis.stansvik@orexplore.com" target="_blank">elvis.stansvik@orexplore.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">2017-05-25 23:37 GMT+02:00 David Cole <<a href="mailto:DLRdave@aol.com">DLRdave@aol.com</a>>:<br>

Alright, that's good. Then we're seeing the same thing.<br>

<br>
Yes, probably.<br>

No worries, I'm free to do as I please with the one I have, so I'll do<br>
some experimenting with different drivers when I'm back on Monday.<br>
<br>
Thanks to everyone trying this out.<br>
