From some time (maybe when I installed one of fonts for subtitles) I have a problem with scaling fonts in few texts. 99% of web pages and PDF files opened in the browser work correctly, but sometimes 1% of them get crashed. To the point, they are enlarged and pixelated. For example, I have it constantly on the website of the polish store "morele.net" or recently in sports articles on newspaper website (see the illustration below). At first I thought it was a problem with the sans-serif font, but then I verified the idea, because the font-family is different on both websites. I tried to fix it by installing default fonts, turning on ClearType, checking at browser flags, but it didn't help. I only noticed that after restarting chrome://flags/ browser settings, for a second after entering one of the above-mentioned portals, the font displays normally, and then changes and refreshes to the broken one.
Does anyone have any ideas to fix this without drastic "reinstall the system" moves?
