having the Effect Controls panel open causes the timeline bar to lag/stutter during playback

The playback of video itself isn't laggy/stuttery, I'm talking specifcally about the blue timeline bar that scrolls while playing. v25.3.0 build 84

EDIT: I should add, when a clip is NOT selected (and the Effect Controls panel is empty) the lagging is noticeably lessened, although still present. 

EDIT 2: Under preferences > timeline > Timeline Playback Auto-Scrolling, the lagging happens when "No Scroll" and "Page Scroll" are selected, but when "Smooth Scroll" is selected, the timeline scrolls smoothly with no lag. I personally like Page Scroll better though.

    disabling GPU accelerated UI rendering fixes the issue entirely, although it's certainly not an ideal workaround in the long run. I'll leave it disabled until hopefully it's fixed in a future update.

    EDIT > PREFERENCE > GENERAL and uncheck the bottom box that says "GPU accelerated UI rendering (restart required)"
