Hi @jiren-uns, as a workaround for the issue, you can try the following: run the Opera GX with the switch as follows: "path\to\launcher.exe" --disable-gpu, then go to opera:settings/system, and disable "Use hardware acceleration when available", restart the browser without the switch, and see if that helps.
I really want to use this web browser, as I find it an amazing browser that has wonderful features. However, only one thing stops me from using this. It is not compatible for Linux. As you can see, even another person https://forums.opera.com/topic/32990/opera-gx-for-linux. Can the developers release a version for Linux? Preferably Linux Mint or Ubuntu. I would really love to use your amazing browser. Hope to see a reply soon.
