Comment 4 for bug 1928138

No, I made it for myself (using another patch (https://bugs.freedesktop.org/show_bug.cgi?id=91393#c31) as a reference for adding i915 module parameter). Not sure if upstream would accept it. This patch doesn't fix root issue but provides ability to disable DRRS power-saving feature which causes it (I didn't find any other way to do that). By the way, Intel® Graphics Command Center on Windows also has an option to enable/disable "Dynamic Refresh Rate Switching" (https://www.intel.com/content/www/us/en/support/articles/000057188/graphics.html).
