Will these commits hit the 2.8 builds of Blender when it gets released, or will it be available in sooner builds for testing?

Changing the Selection Method to Occlusion Queries under User Preferences > System may work around the issue. In Blender 2.8 this will likely become the default (and only) method.

Its highly likely that this bug is specific to your hardware/driver configuration. These kinds of display issues are often caused by OpenGL driver bugs.

FWIW cursor hiding is a feature of Xfixes, see XFixesHideCursor/XFixesShowCursor, although AFAICT the setWindowCursorVisibility/getEmptyCursor trick in GHOST_WindowX11.cpp should work? at least other features like shift-F seem to get away with it.

I looked into locking the cursor so it could be warped, it's not working in the latest weston (3.0.0)
both gnome-shell and weston.

Jonas Ådahl (jadahl) added a comment to T53004: Moving objects (G key) has broken behavior on linux/wayland.

Note that the pointer warping emulation inside Xwayland needs special Xwayland specific hand holding in the compositor. I think weston only has support for the plain Wayland client part of pointer locking, meaning that it wont work. I only know about gnome-shell (or rather mutter) that does the extra Xwayland hand holding.

(1) Using fly-mode in viewport (Shift+f) causes the camera to move drastically and sporadically when the mouse reaches the edge of the Viewport and wraps around it.

TravLR (TravLR) added a comment to T53004: Moving objects (G key) has broken behavior on linux/wayland.

Back in April 20th, I reported a bug to the Wayland team regarding this issue (as instructed by the Ubuntu Google+ community -- long-time Ubuntu user). After the news of the switch to GNOME & Wayland session by default in their newest upcoming release and beyond, I immediately began testing Blender in the Ubuntu 17.10 default session. There were three major issues which made Blender rather unusable in many circumstances (See the bug I posted in Wayland bugtracker: https://bugs.freedesktop.org/show_bug.cgi?id=100740). The three issues are:

ronan ducluzeau (zeauro) closed T52958: JACK sync plays also meta-strips as Archived.

Hi, original purpose of Blender was to produce images from 3D scene.
Historically, there was an audio sequencer decoupled from video sequencer. They were merged by 2.5 re-design.
If you take attention to Edit Strip panel in Metastrip properties, you can see that they are based on Scene, Movie, Image strips properties with a blend mode dedicated to image blending.

The back trace in report indicates crash somewhere inside of Mesa/LLVM. We can not fix that or patch from Blender side, the driver itself is to be brought to a state when it can handle complexity of Cycles kernels.

I understand this is not a Blender issue, however six months after the various bugs were filed, Blender 2.79 still crashes on compilation under Ubuntu 17.10 Beta 2 with LLVM 5.0 and Mesa 17.2.2, even though it appears to me that all reported bugs were fixed.

For workable experience you can simply disable "Continuous Grab" in User Preferences -> Input on a systems which are running Wayland.

Jonas Ådahl (jadahl) added a comment to T53004: Moving objects (G key) has broken behavior on linux/wayland.

I agree that this is not really a Blender bug. This is rather a limitation of how much of X11's behavior we can emulate without turning X11 into too much of a a backdoor into a Wayland based desktop environment. For example, we can of course not make it possible to allow X11 clients to became global key loggers, and in the same way, we cannot just make it possible to allow X11 clients to completely take over your mouse cursor.

Sergey Sharybin (sergey) added a comment to T53004: Moving objects (G key) has broken behavior on linux/wayland.

I do not see any issues in the continuous grab implementation in Blender, and fact that none of X11 servers showed the issue in the past decades backs up theory that we don't abuse anything.

Carlos Garnacho (garnacho) added a comment to T53004: Moving objects (G key) has broken behavior on linux/wayland.

Very sad to see this resolution without any further consideration. FWIW, Xwayland is an X11 server on its own, so clearly not all X11 servers work fine. Furthermore, it's becoming the de-facto X11 server as many distros are switching to Wayland sessions by default. Blender will look broken on all of them.

Thanks for the report, but this isn't a Blender bug, all the X11 servers are working fine. The issue is in Waylan'd emulation of X11 protocol, which we can not fix from our side.

Javier Herrero (jubjub) added a comment to T51252: Menu flickering under wayland unless "Window Draw Method" is set to "Full".

I'm having the same issue with flickering under Wayland, regardless of the draw method used, although full does help a little bit, I also get black flickering of the 3d viewport when circle selecting vertices on wireframe view.
I've verified that this only happens under Wayland, the exact same setup, same drivers and kernel under X11 works just fine.
I'm using a RX 560 with the amdgpu drivers, kernel 4.13, although I tried 4.9 and 4.12 as well.

You could try installing the OpenGL libraries anyway, even if you don't actually configure the device to be used for display in X11, since this error could be related to them being missing. For viewport rendering we try to initialize the device with an OpenGL interoperability for faster viewport display, and if that fails initialize without, but it seems somehow things permanently break there.
