Strange graphical glitches in browser while logged into Roll20

(Repost because first set of images had personal info) <a href="https://imgur.com/a/fSZ1K" rel="nofollow">https://imgur.com/a/fSZ1K</a> I've been getting weird glitches like this since Monday. I'm not sure what's causing them but they only happen when I'm logged into Roll20 and running a Virtual Tabletop. I tried updating flashplayer already.

Before we dive into the guts of the issue, we're going to need you to do a few things for us, things that sometimes fix issues for users before more extensive troubleshooting is needed. Can you please follow Steps 1-3 of our Solving Technical Issues wiki page (temporarily disable all browser add-ons and extensions, temporarily pause your anti-virus, and try switching browsers (for Chrome/Firefox specific issues) ) to see if one of those components is causing the problem. If all of that fails, please follow Step 4 , including providing all of the requested information, so that we can further assist you.
Okay, I cleared my cache, whitelisted Roll20 in my antivirus (Trendmicro) and disabled one of my addons for FF (version 38.0), here are the ones I still have: Adblock Plus 2.6.9.1 Ghostery 5.4.5.1 Noscript 2.6.9.29 Reddit Enhancement Suite 4.5.4.1 Skype Click to Call 7.4.0.9058 I'm running windows 7. Javascript is disabled, Cookies are enabled. I'll go back in and see if it happens again. If it does, I'll copy the console log and paste it here.

It happened again. I had to use CTRL+SHIFT+J instead of K to open the log in Firefox.

I experienced the problem again with all addons disabled. Here it is again (with addons back on), in another tab while I'm working on my campaign. The part that makes me think it's not my monitor is that this never happens when I'm in steam or playing any games. The only thing these incidents have in common is that I'm in the virtual tabletop in Roll20.
Hi Masaioh, How long has this issue been persisting for you? I would enable Javascript as we use it throughout out entire site. Additionally, if that does not work, does this issue happen if you try another browser like Google Chrome?

Haven't tried Chrome, I'll turn on Javascript. It's been happening since monday. Oddly enough, only in campaigns I create, but maybe that's because I use premium tokens and the rest of my group doesn't. EDIT: Nevermind, Javascript is on, that's weird.

Tried Chrome, couldn't replicate it, but I don't really use Chrome so I didn't have any addons. I disabled Skype Click to Call in FF once I learned what it did, and I'm testing it now. Nothing so far, but FF keeps going on about bad certificates. EDIT: Still happens in FF with Skype CTC turned off.
If it is browser specific it is likely to be a cache or addon issue. I would try disabling your addons and clear your cache again just to verify. Does this affect any of your players?

Haven't had players in this campaign yet. I'm thinking it's asset related because our other campaign didn't have these issues and the DM just draws maps on a blank grid. I have no problems in Chrome, but I tried clearing my cache in FF and that didn't fix anything. EDIT: I think it's Reddit Enhancement Suite. The one extension I have that I didn't think would affect anything that isn't Reddit.
I use Chrome, windows 7 32bit and I had white boxes. It only lasted for a short while. This was last friday night/saturday early am. I restarted chrome and logged back in, no more issues.
@Masaioh, Turning off R.E.S. solved the issue for you? If that is the case, just let me know so I can close this post. Thanks!
I've determined that it's either RES or some interaction between Firefox and flashplayer. No issues while using Chrome. Go ahead and close the post.
