The worst offender here are the Firefox and Chrome web browsers. It seems like these get assigned the dGPU or iGPU randomly to different windows. If you get the wrong one you have problems with rendering, such as the title bar goes bad.
For years I would submit a ticket for this, it would seem to be fixed, then the bug would come back shortly thereafter.
I had one desktop replacement laptop that blessedly would let me disable the iGPU and then it would be reliable. My current Alienware doesn't.
