Hello, I have two rendering issues. Maybe they are related, maybe they aren't.
## 1. screen flashbacks I don't remember when it started. Some parts of screen have short random flashbacks, i.e. it shows the content shown some time ago. You can see a short video there: https://drive.google.com/file/d/1ypHdDKiPpeE3SfwsdAwDzR3e-AyN932Q/view?usp=sharing I am not moving the cursor, but it sometimes flashes the previous state. This happens even on lockscreen (=> dom0-related). I remember I have screenshotted it (I can't find the screenshot, though), so it does not look like screen controller issue. Usually, alt+tab; alt+tab (i.e., switching to another window and then back) helps, at least for some time. ## 2. screen rendering freezes This one is likely related to the recent update. Screen rendering freezes completely (except mouse cursor) with kwin in some deterministic cases: * Alt+tab. * Screen rotated by 90° or -90°. (It is fine for 180°.) With Xfwm, I see no such issue. ## Some info about my computer CPU+GPU: Intel i7 7500U $ cat /proc/cmdline root=/dev/mapper/qubes_dom0-root rd.lvm.lv=qubes_dom0/root rd.lvm.lv=volatile i915.alpha_support=1 rhgb quiet rd.qubes.hide_all_usb plymouth.ignore-serial-consoles $ uname -r 4.19.43-1.pvops.qubes.x86_64 Do you have any idea what to do with it?
