[kwin] [Bug 477223] Setting an icc profile causes reduced system performance.
https://bugs.kde.org/show_bug.cgi?id=477223 --- Comment #5 from Rean --- (In reply to Zamundaaa from comment #4) > What hardware is this on? The alpha has some known performance issues on > Intel due to driver bugs. My laptop's CPU is an i5 7300hq. Also, one thing to note is that I did a system update lately, and the higher CPU usage i was having before dropped a little bit even with the icc profile set, and the frame drops lessened a little bit after an update on Plasma 6 Alpha lately. I don't know what caused the performance increase, but somehow it's slightly better. -- You are receiving this mail because: You are watching all bug changes.

Can you test a > live boot of Neon unstable to confirm? There is a kind of bad mouse judder in KDE Neon that is only really noticeable in the overview effect when you have an icc profile set. I know KDE's latest neon unstable has later packages for Plasma 6 than what Arch has currently, so there might've been an update that messed up performance again anyway.

The mouse is again lagging when composer performance drops. I tested this before in the earlier Plasma 6 Alpha, and the mouse lag was completely gone even when the desktop was running at 10 fps. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=472663 --- Comment #12 from Rean --- Also, when readability checks are disabled, I get slight micro freezes as well. I was wondering what was causing that. It seems my Intel iGPU actually get performance issues when readability checks is disabled, and i guess some older igpu's get performance issues with it enabled. This is definitely a strange issue, at least for me. I get way better performance with it on. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=472663 --- Comment #13 from Rean --- Never mind about the micro freezes I mentioned before. After a few days of testing, the micro freezes seem to happen whether I have the readability checks enabled or disabled. Enabling readability checks doesn't make the micro freezes any worse or better, but it makes the mouse lag under heavy loads go away, so I'll leave it enabled since it's not what's causing the freezes; something else is. -- You are receiving this mail because: You are watching all bug changes.
[kwin] [Bug 477223] Setting an icc profile causes reduced system performance.

I know MPV is using allot of my CPU because of all these things, around 60% to 70% according to the quality of the video, but I get no frame drops. The computer is still capable, mostly, but then when the ICC profile is set, that's when frame drops and the stuttering starts. Everything is just a slightly worst experience performance-wise, and games suffer fps drops as well. -- You are receiving this mail because: You are watching all bug changes.
[dolphin] [Bug 485572] Video thumbnails using ffmpegthumbs stopped working within gocryptfs mounts after updating to KDE frameworks 6.1
https://bugs.kde.org/show_bug.cgi?id=485572 Rean changed: What|Removed |Added CC||tech...@protonmail.com --- Comment #1 from Rean --- After this update, I noticed my network drive thumbnails were not showing anymore, and I figured out that the setting Skip previews for remote files above a certain size is set to no previews. That's the reason why it's not showing any previews, but I thought this setting was only for network drives. Why does it affect vaults? That seems like a bug. In Dolphin, go to Configure > Interface > Previews and increase the size of the remote file previews. See if that works for you as well. -- You are receiving this mail because: You are watching all bug changes.
[kwin] [Bug 474725] Screen randomly freezes for a second
https://bugs.kde.org/show_bug.cgi?id=474725 Rean changed: What|Removed |Added CC||tech...@protonmail.com --- Comment #17 from Rean --- I thought this issue didn't affect me before, even though I was indeed getting freezes. I realized it when the patch to disable hardware cursors stopped the freezes on Plasma 6, so I left it disabled, but lately I decided to enable hardware cursors again using the env veriable and noticed the freezing not happening anymore. I don't know what it is; it could be a MESA update or something in Plasma 6 RC2. I don't know what changed, but the freezing issue with HW cursors is suddenly gone. I'm really glad that I don't have to use software cursors anymore because I notice the slowness of the mouse movement under heavy load, and that does not feel nice at all. Hopefully the next thing that gets fixed is the fact that the entire plasma desktop's slows down from a single graphical program running slowly i tested with compositor-killer. -- You are receiving this mail because: You are watching all bug changes.
[kwin] [Bug 477223] New: Setting an icc profile causes reduced system performance.
https://bugs.kde.org/show_bug.cgi?id=477223 Bug ID: 477223 Summary: Setting an icc profile causes reduced system performance.

Use Wayland 2. Apply an icc profile in Display Configuration OBSERVED RESULT Reduced performance, especially when playing demanding video playback and gaming; it also causes higher CPU usage. I even noticed laggy, delayed mouse movement. EXPECTED RESULT Normal performance.

https://bugs.kde.org/show_bug.cgi?id=477223 --- Comment #1 from Rean --- Oh, some more testing I did was with MPV itself. I set the color profile inside mpv's config, removed the one from the display configuration, and then played a high-res video in mpv. The results are the same. I simply get the same frame drops in MPV as I do setting icc from display configuration. I tested mpv in x11 as well with the icc profile set the same way; I didn't change the mpv.config, and there were no frame drops. I also spent time testing KDE Plasma Wayland 5.27.9 with the icc profile set in mpv because it does work there from mpv; you can tell by the colors looking different, so I know for sure it works in mpv under Wayland in 5.27.9, and I also see no frame drops there, so this performance drop issue seems to be specific to setting a icc profile in Plasma 5.27.80's wayland session only. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=477223 --- Comment #2 from Rean --- (In reply to Myself from comment #1) Damn, there is no way to edit a comment I made here, ok, this part where I said "under Wayland in 5.27.9, and I also see no frame drops there." This is wrong; ignore this. I tested again, and there is definitely the same performance drop, just not as bad as 5.27.80. -- You are receiving this mail because: You are watching all bug changes.
[kwin] [Bug 477223] Setting an icc profile causes reduced system performance.
https://bugs.kde.org/show_bug.cgi?id=477223 --- Comment #3 from Rean --- I tested again, and it seems like the reason I didn't see any frame drops in X11 was because when mpv goes into fullscreen, the compositor is disabled, in turn giving better performance. If compositing is allowed, I get the same frame drops in x11, but there is no way to disable compositing in Wayland like in X11 because Wayland manages windows, etc. with the compositor, and if that dies, the entire session dies anyway. I thought the compositing in Wayland was supposed to be more efficient. Why does the compositor cause dropped frames like on X11 and cause applications to get higher CPU usage when using an icc profile? -- You are receiving this mail because: You are watching all bug changes.

[kwin] [Bug 452119] Poor performance on intel igp on wayland versus Xorg
https://bugs.kde.org/show_bug.cgi?id=452119 Rean changed: What|Removed |Added CC||tech...@protonmail.com --- Comment #45 from Rean --- I'm going to add my experience with Wayland and X11 performance. I hope this can be addressed in the future. My Plasma 5.26.4 is powered by an Intel Pentium G2030T (2) 2.60GHz. I tested both X11 and Wayland with blur and contrast enabled as well as the FPS effect. I did the same tests on both X11 and Wayland, and I noticed that any blur effect that fills the entire screen makes the framerate drop as low as 40 in Wayland, while on X11 I get 60 fps with the same blurred window filling the entire screen. Also, I get higher render usage with animations and moving windows around in Wayland vs. what I get in X11. I don't think Wayland's performance should be this bad. -- You are receiving this mail because: You are watching all bug changes.
