This is particularly annoying when I'm trying to practice reading Japanese. The fonts for languages that have very intricate characters are not great, but if I can force my font of choice then I can be sure to be able to read it. You don't need to know what it says, but here is an example of the BBC using their own choice of font: f639f7a1-37a0-468a-b018-dd7c2325e2b8-image.png See the jagged edges on the first character? Compare this with when I force it to use my own choice of font: 4d6f6777-f34d-47e8-94f9-86aacbdb7eee-image.png It's so much less ragged and ugly, and is vastly easier to read, and the font size didn't need to be increased to achieve this - just a change in font. This isn't so much an issue for simple characters, but for the more complex kanji characters it really makes a difference. Some users might argue this is the fault of chrome's poor font rendering, but when we have an easy solution available to us (default fonts) it would be stupid to not make use of it.

Might be a good read about font rendering in Chrome - https://browser.taokaizen.com/chrome-directwrite/

@harukamy フォントとは別口ですが、手元でメモファイルを210MBまで膨らましたところ、新しいウィンドウが開くたびに5秒ほどモタつく現象が発生しました。（同期使用・不使用に関わらず） そちらに関して何かパフォーマンスチューニングができましたら、本件も改善する可能性がありますね。

@Gwen-Dragon In Guest window, it works fine although I get this message 0_1556096178557_21ffd21e-1377-4519-bf61-49cb60192900-image.png I can't make those presentations public since they're owned by the company I'm working for. I tried to open Google Slides also in another window with another user and the issue does not appear. The console log looks like this where I get the error: 0_1556096395410_2f487352-d402-4dea-8e0f-c64896595c5b-image.png

+1 Here is a good example of how bad Vivaldi font engine is/how good Firefox font engine is: Vivaldi alt text Firefox alt text https://forum.vivaldi.net/topic/26087/bold-fonts-blurry-small-continuous-issue

Tip for next time: just rename your profile folder, start Vivaldi and look it up yourself, far easier than checking for an answer concerning any default preferences.

One area where I really want this feature is the notes section -- most of the apps I use text with let me choose the font I'm writing with

@gwen-dragon [the curtain is lowered for 8 days to denote the passage of a week] Yes, setting FREETYPE_PROPERTIES gives correct results in both stable and snapshot.

Попробуй вообще отключить аппартное ускорение: vivaldi://settings/search#hardw Там внутри будет нужная галка. У меня плыли шрифты после захода с магазин расширений или на практически любой сайт, где есть анимация. Данная штука помогла. Каких-то замедлений работы не увидел (видео не смотрю, так как комп рабочий).
