<pre>So, 3 issues:
(1) Using fly-mode in viewport (Shift+f) causes the camera to move
sporadically.
(2) Moving an object (g) and pushing the mouse past the edge of the viewport
window causes the object to move sporadically.
(3) Screen flickers pretty bad during both instances (1) and (2).
DETAILS
What happens in Blender 3D editor is, sometimes you can "fly" through your 3D
scene by entering fly mode (Shift+f in viewport window). This gives you a
first-person camera view and controls similar to conventional first-person
shooter PC games: you can use the mouse and W, S, D and A to move through the
scene.
Problem is, running Blender 2.78c under Wayland produces an issue when in this
fly mode: the viewport screen goes ALL over the place. It seems to be involved
with moving the mouse, specifically.
Under X window system, when you're in fly mode or moving a 3D object/mesh in
the 3D viewport window, once the mouse reaches the edge of the viewport screen,
it will "roll over" to the other side and allow the user to continue moving the
object. The mouse will travel across the viewport window, again, and once it
reaches the edge of the viewport window, it will roll over to the opposite edge
of the viewport.
This issue seems to come up for moving objects as well. Once you press G to
move an object, and move it along a certain axis, once the mouse reaches the
edge of the Viewport window, the select object's position goes ALL over the
place.
The screen also flickers pretty regularly during fly mode (Shift + f) or moving
an object (G) in viewport.
I checked with the Blender dev's, and they said it's not a bug with the
program.
