There is some good feedback here and I’ve made sure it was passed on.
Unfortunately do to holiday, it may be a few days before we hear something back. I believe blizzard devs are on 4 day weekend unless i’m mistaken. Support will still be available (they always are), but they can only do same thing I did, pass the info on. They wouldn’t have any info to pass on until next week either. However, I’m pretty sure there is enough info in this thread for blizzard to work with.
Hey all,
We’ll need more information and reports to look into this in more depth. Can anybody who has this error please post their system specs for us? You don’t need to do the full export of the system report, just the information on the main window about your mac os version, mac model, processor, RAM, and graphics card is fine. Thanks!
Same problem here. Tech/customer service rep. asked me to input the following info in this thread:
-MacBook Pro (Retina, 15-inch, Mid 2015)
-macOS Mojave (Version 10.14.5)
-Processor: 2.8 GHz Intel Core i7
-Memory: 16 GB 1600 MHz DDR3
-Graphics: AMD Radeon R9 M370X 2 GB, Intel Iris Pro 1536 MB
The sky flickers when I click down with either the mouse or trackpad.
macOS Mojave 10.14.5 (18F132)
iMac (Retina 5K, 27-inch, Late 2015)
Processor: 3,2 GHz Intel Core i5
Memory: 24 GB 1600 MHz DDR3
Graphics: AMD Radeon R9 M390 2 GB
Am currently experiencing this issue. As above, it does not occur when playing in a window, and is evident when either the left or right mouse button is clicked independently but not when the right button is used to steer while the left button is being held down. Evident in BFA zones, Stormwind, and BI Dalaran, but does not seem to be affecting Vale of Eternal Blossoms, Darkmoon Island or Shadowmoon garrison. Full reinstall of the game with fresh folders did not solve the problem.
My specs:
iMac Retina 5K, 27-inch, 2019

Processor: 3.6 GHz Intel Core i9

Hey all,
Thanks for all the info thus far - if other players end up with this issue, we’re still looking into it, and the more system specs we can get for now the better. For a work around, most players mention that you can switch to windowed mode to prevent the issue.
It’s especially bad flickering while doing Drustvar’s Shell Game – does it every few seconds.

Same issue on this Mac.

Thanks for being so responsive @ Drakuloth.
I’ve recently switched to an eGPU setup, and am encountering sporadic flickering of the skybox textures. It’s reproducible by simply alt-tabbing in and out of the game client. Detailed specs:
MacBook Pro (15-inch, 2016)
Processor: 2.6 GHz Intel Core i7
Memory: 16 GB 2133 MHz LPDDR3
eGPU: Radeon VII 16 GB
eGPU Enclosure: Razer Core X
Screen Resolution: 3440x1440 (100% render scaling)
macOS: 10.14.5
WoW renderer: Metal
Game performance is excellent btw. TY for implementing the Metal API 
.
Still on our radar - we’d like more reports if anybody else is experiencing this just to get a decent idea on how common it is.
Blimey, had to level up a character to Level 10 to post here!
I appear to have found a solution though:
This bug appears to relate to another bug - the oversized cursor bug! (_See here - https://us.forums.blizzard.com/en/wow/t/my-cursor-and-nameplates-got-bigger/209051_). Using the command ‘/console cursorSizePreferred 0’ this was the only console command for ‘cursorSize’ that solved my issue. Upon my cursor returning to its normal size, the flicking sky textures stopped. Up until that point, clicking the mouse was the trigger for the texture bug.
It seems it appears to be the route issue of this bug, so at least it’s not a separate issue of its own. If anyone else cares to test this and see if it works for them I’d be pleased to know!
Tried this fix and it appears to have worked – sky does not flicker in fullscreen anymore, and is still clear in windowed. One new behavior – it will flicker once when maximizing the window to fullscreen, but not when minimizing. Otherwise the issue does not seem to reoccur.
I updated my OS to 10.14.6 prior to trying this fix and it did not have any effect one way or the other.
Oh, wow! That actually fixed it lol
PS: Also updated to 10.14.6. The update didn’t fix anything, but the slash command did.
Same exact issue here.
Macbook Pro 2015 15 inch
2.8GHZ intel core i7
1600MHZ DDR3 16GB
AMD Radeon R9 M370X 2GB
Intel Iris Pro 1536MB
Worked for me as well!
I moved over to a “new” laptop (same 2015 15" model but a different machine) and had the sky flickering issue appear on the “new” laptop. Tried the console command to fix the flickering and just reduce the giant hand cursor and the fix was immediate.
/console cursorSizePreferred 0
Quoted as this seems to have fixed things for a few players so far. Anybody else get success with Pizzlewhip’s fix? Appreciate you reaching out to let us know what worked for you! The link between the two issues is also good information for the investigation.
I have a brand new iMac Pro with base specs and encountered this ‘click flicker’ issue upon installing WoW yesterday. I can confirm that using the /console command to change the cursor size to 0 has resolved the issue for me as well.
Worked for me.

The console command doesn’t solve the issue for me. It’s still the same as I described earlier. When I position the camera by clicking with the left mouse and dragging, the sky flickers as soon as I release the left mouse button. When I use the right mouse button to click and drag to change the direction my character is facing, the sky does not flicker when the button is released, even though the camera movement is exactly the same.
As before, it depends on what sky texture is displayed. If the sky is covered with clouds, I don’t see the effect as much (or at all). When there are a few clouds, only the parts of the sky not covered by clouds will flicker. The flicker is always black. If I switch to another app, then back to WoW, the problem goes away for a few seconds, but then starts happening again.
All of this is exactly the same as I described it on July 2. Using “Windowed” mode is not an acceptable workaround for me.
