Incorrect behavior in X11 applications when using factional scaling

Incorrect behavior in X11 applications when using factional scaling

Fractional scaling is really a good solution for my 29 inches 4K monitor. The sweet point is 1.5. The icons, text ratio is correct and everything runs fine, only PDF previews on my desktops are broken, and I can live that way. This solution is far better than text font change and other setup that did not work on multiple monitors (because fractional scaling can be set-up per screen) and I use this monitor also with my laptop. The problem is that some applications seem to scale reversely, including some games, Citrix, xman, Unigine Benchmarks, etc.

If I look at the Nvidia X Server Settings application this is what I see.

Incorrect behavior in X11 applications when using factional scaling

My display appears as a virtual huge screen of 5120×2880. It should be 2K resolution for X applications to appear at correct size.
If I try to change panning and viewportin I only obtain strange behaviors, like huge desktop scrolling around or so.

Has someone already experienced this, and found a solution. I’ve got the same issue on my laptop using an AMD graphics card.
