Isn't Super + T more consistent with the existing shortcuts? Solus uses the Super key to move windows, maximize, restore, lock screen and etc., while Ubuntu uses Alt key by default. elementary OS comes with Super + T set, but in Solus you have to set the shortcut for the terminal yourself, because not all desktop users need it.

It's a GTK3 problem and it's a really bad one, because I keep struggling to click something on the edges of the screen. I'll report it in the appropriate place.

I think you're right. I have an eMMC drive. It's much worse.

This issue is being discussed in the task T139 (and it's not exclusive to Firefox). Please, follow its development there. Thanks.

It used to be worse on my computer, but now it only happens when opening the Settings. It takes longer than normal and the cursor lags.

I wrote a new task about that other problem.

You can reproduce this when hovering some images like this.
It also happens within MyPaint application, all over the drawing area. I only have Intel graphics.

It's also a life saver for those with cheap/old SSDs or eMMCs (my case), which must reduce the amount of writes to disk as much as possible to keep it working long enough (can't replace when it's soldered). With 2 GB of RAM, swap is heavily used at least once a day. This wouldn't happen back when I had

zram-config

activated in Ubuntu. zram-config sets everything up automatically.
