Same here, I also have Windows Dark mode enabled.

I have experienced another issue. On the Speed Dial, I can only move/drag the website tiles from right to left.
If I instead drag one from the left and move it on to the right, as I'm holding the mouse button the tile shifts to the left - showing that the one I'm dragging is going to go on the blank space on the right. As I let go of the mouse it jumps back to the left. This only happened when moving a left tile to the right, and not with a right tile to the left.

The screenshot/snapshot tool in the sidebar doesn't capture more than what is seen on screen at the same time. i.e. Before I could scroll down and capture a very tall image of a website from the very top to the footer. Now it seems to cut the top away as I scroll down, so that as I've scrolled/panned to the bottom it only captures this bottom-most screen (and not a long, tall image of the entire website). I've also experienced where it tries to get a taller image but a portion will be grey/blank/un-captured.
It seems to work fine when I am only looking to capture a small portion of the screen.

A bit of trouble explaining but hope you can understand. Could you look into fixing it?

I'm using Opera 53.0.2907.68 Stable (says it's up-to-date) and on Windows 10 (64-bit).

For me it seems to be happening too. Also when I opened Opera (49.0.2725.47) for the first time today it would freeze for a few seconds followed by the window going '(Not responding)' and this too with just two tabs open. I restarted the computer and it seem better for the freezes but I think it uses more CPU% and Memory than it did before. Also Opera Neon is using less memory (like 900MB) than standard Opera browser for the same tabs.

I've restarted my computer and re-pinned to the taskbar a few times and now it seems to be working as normal. Don't know what was happening.

I'm using Opera version: 47.0.2631.55 (PGO), Stable and on Windows 10 64-bit (WoW64)

Just recently, my pinned shortcut on my taskbar said that the shortcut couldn't locate Opera.exe so I manually went into the install directory and launched it. This resulted in Opera opening in a different window/icon on the taskbar. I removed the initial one and re-pinned the new one. Now I've managed to get Opera to launch from clicking the new pinned shortcut but it still opens as a new process/icon/shortcut on the taskbar. I'm unsure of the treminology for these things so I'm linking a small screenshot.

Can someone help me with this, getting it back to 'normal' functionality?
