Speckles/Visual "static" while playing on Wine (Ubuntu 16.04)

[wdana17]

Hi, I made this thread on reddit and someone there suggested I try here.

I've recently gotten back into P1999 (loving it!). I mostly play on my gaming rig, but decided I wanted to put in on my Linux laptop for playing when I'm traveling. I didn't have much trouble setting it up with Wine -- just copied over my Windows installation -- but I'm having this weird issue where I have these little black dots running all over my screen constantly (only in-game). They appear for a fraction of a second and move constantly, like static on a TV, and appear both on my external monitor and the laptop's built-in screen.

Here is a screenshot: https://imgur.com/TrRjYZQ

The game is otherwise very playable (and of course fun!). Just wondering if anybody else had seen this sort of behavior before, and hopefully found a solution. I've tried this with both the default UI and Duxa UI; same issue either way. I googled around but didn't find much; thanks!
