This bug is not related to any settings or GPU / CPU load or something, neither anything in the community folder.
There is NO any proper workaround.
It’s a DX12 bug, and it’s there since many months now…
It totally prevent me for using DX12 which is a shame cause everything work flawless except this.
I had this problem too with my RX7900XTX. After uninstallation and rerinstallation of MSFS this proplem is gone. No texture issues anymore in DX12. I can swith between views as often as I like . maybe consider a new fresh imstall of MSFS.
I have a 13700K and RTX4080. This problem appeared at some point and I believe it had to do with the update to Fenix v2. For me the problem doesn’t appear with the FBW A320. I am using DX12, FG, FS Realistic, GSX Pro, FSUIPC. I had to stick to FBW A320 just because of this issue, it is awful.
It has nothing to do with any addon as mentioned several times in this thread and elsewhere, it is simply a DX12 bug not yet resolved by the devs and with only workarounds available “fixing” it on a very transient basis.
The most interesting thing with this bug (and probably the reason why it is still not eliminated) is the total impossibility to pinpoint it to a specific root cause. In my case for example, switching from a RX 6900XT to a RTX 4080 almost completely eliminated the appareance of the bug on my rig, but it still happens occasionally without any recognizable pattern.
Do you have the same issue if you follow the OP’s steps to reproduce it?

I have the same issue, but am not using REX textures. So it’s not that.
I noticed that this problem is only occurring when I use the fenix a320. When I use any other native or non-native aircraft, it does not occur (I don’t have pmdg).
I’m using dx12, dlss quality, dlss frame generator, ultra settings.
Wish there was some feedback on this from the devs.
Terrible tile popping/texture bleed in SU12 - DX12, rtx4080, latest Nvidia driver (and earlier versions).
No reports of any fix in SU13 beta notes…sigh…
Honestly can’t remember I had this with my 3090 though…
Hello community! I was taxiing around DFW to demonstrate another issue at KDFW. I happened to come across this error as well. This was with a cleand DX12 cache and clean community folder.
Been having this issue for a while really hit and miss, but so glad I’m not the only one with this!!
Haven’t tested moving back to DX11 but hoping this can get fixed.

Bing terrain seems to be popping through sparsely at all airport surfaces and terrain in SU13 DX12 Beta (so far has occurred at default VQPR, Drzewiecki KEWR, MK Studios KPHL, MK Studios CYUL)… didn’t have this issue with SU12

noted that it´s getting worse with the Fenix A320, less bing tiles with PMDG but still existent (see photo from LIRA)

Happens too at RJOO and Beijing Airport. Even with third party airports in the most secluded airports (NZAA)

Interestingly with SU13, latest graphics drivers and Pushback Toolbar (freeware addon) removed, I did not notice the behaviour. Completed a few flights now, online/VATSIM, FSR2 on DX12, FBW A32N. Runs surprisingly smooth. Dont know if it is SU13 or the pushback toolbaar thing to blame, i suspect the latter.
SU13 DX12, 5800X3D, 6900 XT on latest drivers.
Thinking about this…as for some people, this seems to occur in the Fenix A320 or the PMDG (dont have those): Do those acft have some sort of a pushback/“map view” system integrated? In the FBW 32NX, i deactivated the integrated system alongside the “Pushback toolbar” freeware in favour of now using GSX, so I am wondering if having a second (external) camera view active somewhere might cause the issue?
Seems even worse in SU13 for me, and I can’t see a pushback service causing this. I do not use Pushback Toolbar and have this issue.
I’ve said it earlier in the thread. I have the issue even when I run a pure “vanilla” install of the sim.
It’s a bug with the sim. There may or may not be add-ons that exacerbate the issue, but it remains a core sim issue.
Do you have the same issue if you follow the OP’s steps to reproduce it?
Yes, same ussue.

Missing texture tiles at airports when in DX12.
If relevant, provide additional screenshots/video:
The sim runs so much better with DX12. It is a pitty that I have to accept this texture problem. It really kills the immersion.
I am getting the texture issue only with Frame Generation on. Otherwise no issues. It is a bit of a shame that this issue has been persistent throughout users for a while and no fixes have been made.
