Driver 6.4.6-1 is a downgrade from Driver 6.4.5-5

My tablet pen used to work normally, but then it took an update to the knee.

Before the update, using a button that summons a radial was instantaneous. After the update, it takes half a second, and after you pick an option from the radial, it leaves the name of the option hanging on top of your screen for some seconds (which gets in the way). But the worst part is the constant driver crash whenever you try using a radial. Like, if you used a radial shortcut, it's very likely the driver would crash before you got to the 10th use (I'm usually using the "undo" on this). When the driver crashes, you're forced to either restart the computer or restart the driver through the "services" menu. And even then, this step sometimes fails. Well, thankfully it got solved when I uninstalled it and went back to the previous version of the driver.

EDIT: Just discovered something very important about this. I thought the new update brought this problem, but it actually didn't. The new update brought a revamp for the radial HUD, which happens to be a little slower. I use the radial with the "pin" option, which makes it not disappear as soon as I hit a button. I'm used to opening the radial with the pen button, choosing one option and then closing it with the same pen button (since it's pinned, it won't close on its own and you need to re-press the pen button for it). However, there's a bug that if you choose an option in a pinned radial, and immediately press the button that opens / closes the radial before the option you picked can take effect, it 100% 10/10 insta-crashes the driver. It was already a thing before the update. But since the radial is slightly slower in the new update, it also made the bug easier to manifest.

The easiest solution is not using a pinned radial, just so you don't manually close it too fast and crashes the driver.

EDIT (again): Even though the above solution seemingly stops the bug from occurring, it may still happen very rarely with the undo / redo shortcuts on radial. Specially if you leave the pen pressed on it and watch as multiple things get undone / redone. So I suppose doing the previous solution + not putting undo / redo on the radial shortcuts is the ultimate solution to avoid the driver crash.

Also, please fix these... All the crashes, some way or another, seems to come from the radial...
