--- Comment #3 from Simon <simon.adr...@ieee.org> --- Another update: 1) I wrote that the problem also persists with 100 % scaling. This is, at least now, no longer true. The problem does not exist with normal scaling, but only with fractional scaling. 2) It seems to be related to adaptive sync. I had used "automatic" as option, which allowed normal desktop usage, but made the problems with full screen videos. If I select "Always", my desktop basically freezes (at least, when there are some applications open). Deactivating "adaptive sync" seems to fix my problem. I need to do some more long term tests. -- You are receiving this mail because: You are watching all bug changes.
