As a developer that has only access to Linux for various reasons, i am forced to boot a VM only to do my testings with Opera gx, as all others Browsers are available directly. Which is a significant testing overhead that just pushes me to say 'sorry i'll fix this opera GX bug in 10 days alongside all other bugs on opera GX i've collected during this period to be time worthy.'. And this despite the bug being easy or hard to fix, just because it is annoying to have to work with VMs.
Hence why i'd ask for a OperaGX support on linux
