MPO Issues

On Windows 11 25H2, with the latest AMD drivers (and even with the outdated drivers windows updates provides), I am experiencing two issues caused by MPO. I am not sure whether each issue is independent from the other or not; however, disabling MPO fixes both.

The first is this bug. For this bug, one simple solution (or workaround) instead of entirely disabling MPO is to use a static text select cursor instead of an inverted one (which changes color depending on the background).

The second bug I'm having is detailed in these two posts, and more comprehensive fixes are in the second post:



However, both the registry key fix (without disabling MPO entirely) and the vivetool fix do not solve the first bug I'm having. I have also realized the vivetool fix alone doesn't fix the second bug (the scrolling bug, where parts of a webpage freeze while scrolling), but applying both the vivetool fix and the OverlayMinFPS fix seems to solve it.

So, three fixes are required to fix these two bugs. Entirely disabling MPO solves all of these bugs. However, I would prefer to not go that route, in order to not lose some performance benefits that MPO provides.

My question: is this combo of fixes good, or does it mean that MPO is causing some issues under the hood which may degrade performance, given that fixing the second bug doesn't fix the first bug?

Should I disable MPO entirely and undo these fixes, or just keep using the fixes? I assume disabling MPO provides superior stability at the cost of some performance, but I would like to get opinions from knowledgeable people. Since the first bug isn't fixed by the fixes of the second bug, I would guess MPO is still causing some issues which I have yet to discover.

I should also add that dxdiag reports "MPO MaxPlanes: 2." Does this mean that performance benefits of MPO on my system are minimal since there is a maximum of just two planes?
