<![CDATA[[Visual bug] White squares show up at random on Opera GX]]>I've been having this problem at random for a few days now. White squares or boxes flash over the screen before disappearing.

I haven't been able to get a screenshot of it in action since this glitch only lasts for a few frames, so here's a recreation of what it looks like:

I've noticed this tends to happen more often on Youtube, and disabling hardware acceleration seems to prevent this from happening.

In case this is hardware related, my specs are:
CPU: AMD Ryzen 7 5700X @ 4.5GHz
GPU: NVIDIA GeForce RTX 3060 Ti
RAM: 16GB @ 3200 MHz
And I have a 165Hz monitor.

I recently set my memory clock to XMP. Could that have something to do with it?

I'm also using a custom made Mod with a video background, but I haven't encountered this bug on the Speed Dial.

Turn off either of them, for my liking, i would leave Youtube's only, bc Opera's brokes some grey parts like description. Up to you ofc.

Go to opera://flags and set #use-angle to OpenGL or anything that's not undefined

This bug or whatever has been happening to me for the past 2-3 weeks, so 3 days ago I swapped to Brave hoping it wouldn't do that too but that also has the same thing as well.

I set it to OpenGL now. Also, I set #enable-vulkan to Enabled because why not. I'll update after a few days of use to report if the bug is still happening.

Opera GX, along with many other browsers are based on Chromium, so they inherit its bugs in some way. Which sucks, because if that's the case, it means there's not much the GX devs can do.

Though this is mostly just speculation on my part, I haven't tested with other Chromium based browsers. I'm just going by what I've read online.

It started recently in the last two weeks maybe, and it is only on my second display. However that could just be because I only watch videos on my secondary display.

My specs are as follows:
Intel i5 9400f
NVIDIA RTX 2060 Super
16GB RAM
1080p 144hz monitor and a 1080p 60hz monitor

I don't use RGX, my GPU is overclocked, and XMP is enabled. My hypothesis though is that this doesn't have anything to do with hardware and is likely a Nvidia driver bug specific to Opera GX. I would like to know what websites cause this for you guys, and I think that ReelBigDan is probably on to something with the issue stemming from website elements.

Intel i7 6700k
RTX 3080
64gb RAM
Acer X34 @ 95hz

No overclocking enablled.

Ryzen 7 5800X
RTX 3060 Ti
16GB RAM
1080p monitor @ 60Hz

I feel like I see the issue most consistently on websites that generate elements on hover (ex. hover over an image to see tags).
