Before reporting your issue

• My copy of Geckium is up to date (no update option in the hamburger/spanner menu)
• I deleted the entire "chrome" folder from my Firefox Profile, if there was one, before installing Geckium

What browser are you running Geckium on?

Mozilla Firefox

What Operating System are you running Geckium on?

Summarise the issue

AFAIK it has affected users using windows and mac, and is annoying for me

Screenshots

How do you reproduce the bug/inaccuracy?

1. open a new tab page, the issue should be apparent

High DPI thumbnail preview image creation issue. Need to figure out a way to prevent this.

This bug seems to happen to me when I move Firefox to my main monitor, which is 2560x1440, yet the tab was last rendered on my secondary monitor which is 1366x768. This might be a bug relating with relying on current window size instead of the size of the rendered contents. Same bug happens vice-versa, except it crops the thumbnail instead of having black areas

Are any of the monitors running a different DPI setting?

Nope, both are 96 DPI.
