Seems like there are multiple issues here.

One of the issue is that a wrong buffer is used to redraw a part of the screen, but should have been done in their specific offscreen buffer.

Might be an issue in the window manager.

The gpu matrix when drawing both offscreen images to the screen is incorrect.

When rendering correctly:

ModelViewProjectionMatrix {0.00104, 0.00, 0.00, -0.99961}
{0.00, 0.00185, 0.00, -0.99931}
{0.00, 0.00, -0.01, 0.00}
{0.00, 0.00, 0.00, 1.00} float4x4 (column_major)

When rendering incorrectly:

ModelViewProjectionMatrix {0.00132, 0.00, 0.00, -0.9995}
{0.00, 0.07692, 0.00, -0.97115}
{0.00, 0.00, -0.01, 0.00}
{0.00, 0.00, 0.00, 1.00} float4x4 (column_major)

So it seems like the viewport matrix is changed
