Various multiple monitor issues on Surface Laptop Studio (1) since driver updates.
Issues started directly after NVIDIA - Display - 32.0.15.7344 or Surface - Extension - 14.54.139.0 both installed on 2025-10-21
Issues occur when a second monitor is attached, and either extend or duplicate screens is selected. Using only one screen has no issue. Checked with different cables, bypassing HUB and different monitors. All show the same issues.
Issues are (but not limited to)
- 3D (Vulkan) applications in non full-screen mode glitch with a triangle like tearing between the frames.
- This is a screenshot from a derivate of the Vulkan tutorial. To illustrate the tearing I alternate the clear colour to black and green.
- With only one monitor selected (either one) the green flashes as expected. With two monitors, even with duplicate display(!), this tearing which seems to be the presentation not waiting for the chain to finish rendering. Again this was all fine before the update. In borderless full window mode it is okay, as the NVIDIA driver doesn't use the INTEL integrated swap chain.
- Clear type tech is not working, and text is chroma distorted. Happens in all apps, including Microsoft ones.
- I can literally have an app like visual studio running on the second monitor and the text has serve chroma distortion, and then I change monitor setting to just that monitor and the text is correct. and back and forth.
- General glitches on apps when resizing, frames of windows appear for a second.

Update:
These appear to be two different issues. Well there was two updates!
Clear type issue seems to be issue regarding the surface extension which has "broken" my Microsoft travel hub, used for second monitor. replacing with a third party hub has fixed this, but turned my travel hub into a paper weight.
Vulkan issue seems to NVidia driver. I can now select integrated (Iris) or Discrete (NVidia) and issue only occurs with NVidia. In fact it only occurs in windowed (when it needs to use the integrated for the present) dual monitor (but either monitor) and using MAILBOX presentation. I have noticed that the little Alt-Z reminder pops on even for windowed mode, although that only used to happen for full screen. Maybe related.Since the issue started after the driver update, consider rolling back to the previous stable NVIDIA driver version that was working fine. You can do this via Device Manager or using DDU (Display Driver Uninstaller) to completely remove the current driver before reinstalling an older version.
Hi, yes I have tired that (more than once). I am thinking its the other driver as this seems to be involved with the second monitor/dock. However, I can not seem to locate this in the device manager.
