Seen this recently with a user. We haven't quite figured out what combination of items was the contributing factor yet, but here is what resolved.
Open Settings and click the Display option under Win10. On Display page is ''display scaling''. If on, turn this off. For my user, it was on. As soon as disabled, ALM then appeared fine. Also the user was able to turn display scaling on later as well and still have positive ALM results. He mentioned he had to adjust the resolution a bit when he amped up the scaling setting.
Point being try turning this off (defaulting then back to regular 100%) and see if that makes the difference for you. If you need the scaling for any reason, can try turn engage it again to a custom level and see what happens. As with my user, you might have to adjust resolution. He did wind up just leaving off the scaling as ALM was the necessity vs. any other applications.
And not sure if it matters, but tablet mode if on could be a factor. It did not seem to affect my setup, but your mileage could vary.
