Summary0012244: screen partially trashed after resize
DescriptionOn Longhorn (GPU rendering) visualizing a 2d dataset that has a large ratio (w/h) I am seeing that about 5-20% of the width of the view (slice, surface, or LIC representation) is cut off on the right side. This cut off area still takes on the background color until the window is resized at which point the area becomes trashed (attached screen shot). The size of the affected area seems to a be a function of the window aspect ratio.It happens whether I use 1 process or more.

Steps To Reproduceopen data
resize screen

 On longhorn, I am assuming you are not using mesa. In that case any time you are asking OpenGL to create a buffer of size larger than the actual display, you'll have issues. Do you think that's what you are seeing here?

 I am using nvidia driver's opengl.

I think you may be onto something here, the remote display is (1280x1024) while my desktop display is (1900x1280) so it is easy for me to exceed the remote display size.

Is this something PV should handle gracefully?

 Try running pvserver with --use-offscreen-rendering. It uses FBOs, if available and then the OpenGL/screen size restrictions don't seem to have effect. Of course it will still your hardware acceleration, so nothing should change in that respect.

Does that help?

 Using offscreen helps for the surface and slice rep. But when using the LIC rep. the screen still gets trashed, in the same way.

 added a screenshot of the LIC rep using offscreen rendering.

 A work around is to configure the server side display with a high resolution such as 2550x1920,a common resolution for a 30" monitor. most users won't exceed this.

 Will reopen if this starts becoming a major problem for customers.

 Umm, I changed my mind. Leaving this open for now. Let's see what we can do.
