[Bug] [Important] Bright flashes
-
@edwardp After testing KDE, XFCE, GNOME i can confirm. That is a Chromium trouble, i can not see a issue with Firefox.
-
@DoctorG I don't have any special graphics drivers installed, both of my desktops are using the x dot org radeon driver.
-
@edwardp The issue does not depend on any special GPU or driver. Chromium & Vivaldi has the bug, but not Google Chrome. We live in a browser hell.
-
@DoctorG It's obviously out of our control. Hope the Chromium team can fix it.

Something with hardware acceleration changed for me since the jump to Chromium 112 in the Vivaldi snapshots.
Because of an issue in Chromium with when running a high refresh display and a second lower refresh display, prior to 112 I had been running vivaldi with
--use-gl=egl
. I didn't have any random flashes.After the snapshot channel upgraded to Chromium 112,
--use-gl=egl
resulted in hardware acceleration being disabled.Now, running vivaldi-snapshot without
--use-gl=egl
(along with enabling the flags: Override software rendering list, GPU rasterization, Zero-copy rasterizer and Vulkan) has hardware acceleration working and has my multi-display high refresh rate issue resolved. But, I have occasionally gotten the random white flashes when loading up multiple tabs.I did not notice any random white flashes when I was running without hardware acceleration.
To me, the random white flashes seem like they are blank tabs showing up for a second. But this happens when I open a bunch of tabs in the background (like a Speed Dial folder).

These white flashes are unbearable, looks like some Chromium & Vivaldi bug.

I still have Hardware Acceleration (HA) turned off in Vivaldi, due to the Xfce weather plugin erratic scrolling, when HA is turned on.

All this flash with Vivaldi before window and UI is build is the reason why i do not use Vivaldi on Linux.
I am old and do not like bright windows
