alacritty: Incorrect DPR when launched in a second monitor
Hi,
I encountered phenomena similar to #71.
When I launch the app from a second monitor with DPR 1, it displays the half-sized display in a correct size window. When I move the window to the main monitor with DPR 2, then it displays correctly, and when I move it again to the second monitor, it also displays correctly, although the log reports that it changed DPR 1 -> DPR 2 -> DPR 1.
On the other hand, when I launch alacritty from a primary builtin monitor with DPR 2, it works fine.
(It seems that “DPR 1” has already been detected before the display is drawn, but the display does not reflect it. I have checked the code and tried some changes, but cannot figure out how to run something like terminal.resize(size_info)
inside the initialization process. What changes shall I try?)
Action | Monitor | Monitor DPR | Logged DPR | Expected DPR | Actual DPR |
---|---|---|---|---|---|
Launch | secondary | 1 | 1 | 1 | 2? |
Move | primary | 2 | 2 | 2 | 2 |
Move | secondary | 1 | 1 | 1 | 1 |
Action | Monitor | Monitor DPR | Logged DPR | Expected DPR | Actual DPR |
---|---|---|---|---|---|
Launch | primary | 2 | 2 | 2 | 2 |
Move | secondary | 1 | 1 | 1 | 1 |
Move | primary | 2 | 2 | 2 | 2 |

I have upgraded my macOS from High Sierra (10.13.6) to Mojave (10.14.6) and got a correct display with the same binary as what I used to see incorrect display on 10.13.6. So, confirmed that this is only an issue on 10.13, which is now 3 years old. Sorry for the disturbance. Thanks!
Yes, that is why I want to check other environments. Although security update was provided for 10.13 1 month ago (on Sep. 24), the first release of 10.13 was 3 years ago (on Sep 25, 2017).
I don’t have anything as of now. I’d like to check whether it can be reproduced in environments of macOS users around me.
Could you try this patch:
It shouldn’t fix anything, but it will make your
alacritty -vv
log more useful. I’m curious only about the broken case of 1 -> 2 -> 1.OK, I checked with
0.5.0 (a6681e3)
(both downloaded one and built one) and got the same result. So, this is not a regression after 0.5.0.
