Summary0003784: Mouse view desyncs when using SR50
DescriptionWith 0003314 fixed, a new issue was brought to light: when using SR50 (the one-key implementation as seen in Steps To Reproduce), your view gets slightly desync'd and snaps back to an angle roughly 1 tic before you pressed the SR50 key. This only happens when smooth_mouse 0. This problem was also present in older versions of GZDoom, but it has since been fixed there. Unfortunately, I wouldn't know where to find it, but I'd assume all that must be done to resolve this is to port over their mouse fix.
Steps To Reproduce- Add the one-key SR50 alias seen here:'https://zandronum.com/forum/viewtopic.php?t=469 [^]'
- Press the SR50 key while doing hard turns;
- Notice your view "snapping" back at the immediate previous angle you were looking at before pressing the SR50 key.

After further testing, it's been discovered this only happens with uncapped FPS, so there's a chance the problem might not be associated with the mouse code, but with the renderer instead. With capped FPS, there are no such visual problems.

I can't seem to replicate this bug with 3.1 in both renderers. Maybe someone can post a gif or video.

I've recorded a video illustrating this bug for a minute. I press the SR50 bind as I turn during my strafe-runs here. Notice my view jerking ever-so-slightly in the opposite direction every time I activate SR50. It's perhaps easiest to see in the middle of the video where I'm mashing the bind. I recommend going frame-by-frame to get a good look at what's going on.
