TL;DR - Blender Progressively loses framerate during use. Everything lags after a few minutes of use even with a extremely low poly object.

Hello! Im currently working with Blender on a Surface Pro 8! I know, its a bit of a hassle but I've managed to push through and get used to using essentially a tablet monitor!
However there has been a reoccurring problem while in Blender from the moment I installed it. -

I've noticed every time I've used blender on my surface, the program would begin to gradually lose frames more and more as I went on using it. This appears to happen regardless of how detailed my mesh is. There are no modifiers active.

At first, I assumed there was some sort of Cache system in play that's causing blender to lose frames gradually. I assumed that the edits I've been making to the vertices was filling up some sort of video or memory cache. From there I assumed it was possibly the Undo history as well... But I'm starting to think there is something else as I cannot find a way to manually clear said presumed cache. Normally from what I've read, people only experience input lag: delayed edits to their mesh mainly due to extreme poly count and what not. However maneuvering through menus and rotating the viewport remained at a constant High FPS.

This isn't the case for me. Everything is slow. From using the menus to rotating, panning, and zooming in on the viewport.

Next I turned to video memory. I have 8 GBs of RAM in my Surface and I know for a fact that the simple meshes I've been messing around with should not be enough to cause the program to lag as it is.

So far the only fix I've really come to use is simply just to save and restart Blender whenever it gets bad enough to where It's a pain to manage. Upon restart, blender runs extremely well, up until I start making changes to the mesh again. From there the gradual decline of frames begins once again.

I haven't had any luck looking around. Im assuming its just cause im using a Surface Pro 8 but even then, the specs are well above enough to properly run Blender especially with low to mid poly models. Any ideas would be great!

Hi, thanks for the report
This issue has been reported before on a few intel integrated GPUs. See: #86778 (Viewport Slowdown on 11th gen Intel Xe graphics)
I'll merge this report
