Not sure if they meant the player or the main DoM.

In the main application.

Seems OK on Linux.

On macOS the inter_size etc. in GLVideoView::set_image look right but on screen the image is the right width but not high enough (683x252 when it should be 684x370).

Tried with wxWidgets 3.2.3 and it makes no difference to this bug.

Player does the same thing.

No idea what is going on here. Maybe try to check with no texture, to see if that's somehow the problem.

After making the DoM player more and more like the working "cube" sample it seems that the bug can be fixed by replacing WXGLSetCurrentContext(_context->GetWXGLContext()) with _context->SetCurrent(*_canvas).

But doing the same fix with the separate render thread causes a lot of problems. Maybe this thread is related: https://forums.wxwidgets.org/viewtopic.php?t=48301

Perhaps the only solutions are to a) single-thread the GL viewer (so make it work like the simple one) or b) use Metal (maybe?)

Dropping priority since it's a lot of work and fairly edge-casey.

Looking at metal backend on metal branch while I have a new mac.
