Fusion 12 w/ Big Sur Display Flicker

Just upgraded to Big Sur and, among other issues, my Windows 10 VM flickers in full screen mode. It did not do this in Catalina using the same version of Fusion.

My system is 2019 15" Macbook Pro i9 with 32GB RAM.

In full screen my display flickers but not in windowed mode. My display is a Dell U3818DW running at 3840X1600. Again this worked yesterday before upgrading to Big Sur.

I am seeing similar after Big Sur upgrade with Fedora 33 and FreeBSD 12 VMs.  Every time there's any activity, e.g. move mouse; I type into a terminal, or it outputs text; the background brightens and dims repeatedly.

Have you verified that it's on the latest virtual hardware?

Same issue on MacBook Pro (Retina, 15-inch, Mid 2015) with Big Sur and Fusion 12!

Hardware version for the vm is 18. That is the latest I believe.

Me too. Happens whether I'm using the Retina display or external monitor.

I tried the usual suspects, like disabling graphics acceleration, reinstalling VMware tools, without success.

It's almost like the computer is trying to do True Tone colour adjustment whenever you move the mouse about. It's very distracting.

Just upgraded to Big Sur and same issue here with Fusion 12 and Windows 10 and other VMs. Please please suggest a fix. I really need to get work done on Windows.

TEMP FIX: I ended up opening the VM Settings window and overlapping it with the fullscreen VM window and that removed the flicker. The moment the overlapping window leaves the full screen, the flicker comes back on!

I experienced similar issues. I turn off True Tone and everything works fine.

Same problem on all my VMs, regardless of the OS.

Tried with and without graphics hardware acceleration, same result, the flicker persists.

Every single time Apple updates MacOS, Fusion breaks in some way. It's becoming annoying.....

I managed to get it to stop flicker by having the mini-bar always visible (just add it to where it bothers you the least)... but that is a hack that I don't want to use for an extended period and hope VMWare fixes this asap!

I'm getting this problem too on fusion 12.0.0, mac os big sur. It seems to be OK if the mac is using the discrete gpu. With the integrated gpu the colour flickers. Windows 10 x64 guest.

Me too, full screen flickering on a 2020 13" 4 port MacBook Pro with 32 GB of memory, running Big Sur / Windows 10 2H20.

@HSomb 's workaround (keep the mini-bar visible) so far seems to be working - thanks!

Another weird problem is the colour of the cursor in windows guest (mac os big sur host) - when night shift is activated the windows cursor still appears in brilliant white sometimes.

Temporary fix for me is turning off Night Shift schedule.

Hi, In the VMware Fusion menu bar, click View > Full Screen Minibar > Always Show fixed my issue, enable 3d and Retina doesn't matter.

I'm getting the same but only on my external Benq monitor - the retina display on the MacBook Pro seems unaffected. It started when I upgraded to Big Sur but only happens for VMware, all other Mac applications are fine. It seems to relate to how much is going on, for example when the VM is booting up the Windows "Window Pane" graphic pulses about once a second and when I move the cursor or hover over things like shut down it also flickers. Seems to reduce a lot if I don't do anything (not a solution!). The full screen minibar fix didn't work for me
